Tsavo Highway

Tsavo Highway is the fourth campaign mission of Halo 3. Upon completing it on Normal, Heroic, or Legendary the player will unlock The Road achievement. If a player gets up to 15,000 points in the meta-game he or she will unlock the Cavalier achievement.

Summary
This level introduces new drivable vehicles to the player and is meant to allow a player who may be unfamiliar with the game to have some time to get a feel for the controls and physics of vehicles.

Plot
After successfully evacuating the Crow's Nest base, SPARTAN-117 finds his way to a couple of Warthogs and leads a batch of Marines out of an underground tunnel. He then leads the surviving marines through Tsavo, to the town of Voi, where a Pelican drops a pair of Troop warthogs and one regular M12 (with M41 LAAG). After fighting wave after wave of Covenant troops, SPARTAN-117 breaches the barrier blocking the path leading to the ancient Forerunner artifact, buried beneath the Earth's surface.

{Gameplay}

The Chief starts to wake up.


 * Gunnery Sergeant Reynolds: "What happened?"

''The Master Chief comes to in the wreckage of the elevator, with wounded Marines being treated and other Marines trying to regroup. The elevator shaft above is engulfed in flames.''


 * Lieutenant Commander Miranda Keyes (COM) (Signal with much static): "Chief, please respond. What's your status over? If you can hear me, find transport. Head for the town of Voi."


 * Wounded Marine: "Ah! I've got a broken rib."


 * Marine Corpsman: "Hey. You wanna bleed out?"


 * Wounded Marine: "No."


 * Marine Corpsman: "Then I've gotta keep pressure on the wound."

On the other side of the underground vehicle maintenance bay, a Marine Sergeant shows up at the other side of the elevator wreckage and begins to handle the situation.


 * Gunnery Sergeant Reynolds: "(Coughs loudly) Settle down Marines! Somebody hit the emergency power. (Cough)".


 * Marine: "On it, Sergeant."

or or
 * Marine: "Another bombing run?"
 * Marine: "Did we get everyone out sir?"
 * Marine: "'You think the Brutes know where we are?"


 * Marine: "Any word from Charlie 02? We got separated."


 * Marine: "Nah, man. Alpha 06. They're all gone too."


 * Gunnery Sergeant Reynolds: "If you can walk, set your boots on the line."

The Master Chief and any Marines fit for duty form up on the other side of the maintenance bay, with two Warthogs parked and functional.


 * Marine: "What's our situation, Sergeant?"


 * Gunnery Sergeant Reynolds: "Not sure, can't reach the Commander, too far underground. Chief's got the right Idea, Let's mount up, Get the hell outta these caves."


 * Marines: "Yes sir!"

If the Master Chief gets into a Warthog first or opens the door,


 * Gunnery Sergeant Reynolds: "Chief's got the right idea, Lets mount up, get the hell out of these caves,"

The Master Chief and Marines get in the Warthogs.


 * Marine: "I'll get the door sir."

The Marine opens the door (or the Chief can too), and the Warthogs proceed down the tunnel.


 * Gunnery Sergeant Reynolds: "Second Squad! Coming through!"

The Warthogs take out small resistance at the gate leading out of the caves, and head out.


 * Gunnery Sergeant Reynolds: "Don't leave any of 'em standing."

or
 * Gunnery Sergeant Reynolds: "Conserve ammo. Run 'em over!"

or
 * Marine: (Looking at the fleeing jackals) "Look at the little bastards run!"
 * Marine: "Surprise, crap-face!"

''After taking out a fleeing Lance they observe the massive wreckage from the Mombasa Orbital Elevator, along with a crashed Phantom. The Chief finds a cliff and sees a long line of the elevator wreckage.''


 * Female Marine (COM): "The Mombasa Space Elevator."


 * Marine (COM): "It collapsed when the city got glassed."


 * Female Marine (COM): "But the tower was thousands of kilometers high."


 * Marine (COM): "Yeah, well now it's scattered all over the Savannah."


 * Female Marine #1 (COM) (Astonished whisper): "Holy crap!"

The Chief listens to a radio transmission from the wreckage of a crashed Phantom


 * Unknown Brute Commander (COM): "Chieftains! Rally your packs!"


 * Unknown Brute Commander (COM): "Kill all survivors, let none near the crater!"


 * Unknown Brute Commander (COM): "The Prophet will soon complete his blessed task!"

The Warthogs continue on.


 * Gunnery Sergeant Reynolds: "Chief, still can't get the Commander. COMs are a mess, Pelicans are scattered. Best thing now, get some distance between us and the base. Brutes are gonna be looking for survivors."

The Warthogs reach another crashed Phantom and kill the troops around it.


 * Unknown Brute Commander (COM): "I see it, pack brothers! The Holy Relic! What fools, to live so long on hallow ground! Never know what lay beneath the surface."

''The Warthogs keep pressing on, encountering a Phantom and its many troops. The Phantom leaves and it doesn't take long before the Warthogs overpower the infantry.''


 * Gunnery Sergeant Stacker (COM): "I repeat: My convoy's been hit. I've got wounded...(static). We're on the Tsavo Highway about...(static)...east of Voi. Someone, anyone, please, respond! (Static and cut-off).


 * Marine: "Tsavo Highway is just ahead, Chief."

''The Warthogs arrive at the Highway, encountering Brute choppers and several infantry hostiles. One chopper rams and destroys a fully manned attacking Warthog, followed by another Chopper.''

If the Chief dismounts the vehicle and goes into the small checkpoint where Sgt. Stacker is located.


 * Gunnery Sergeant Stacker: "We were en route to Voi Chief. Banshees jumped us, started strafing...Pretty much ruined our day."

After the Covenant who attacked the Supply Convoy are finally defeated, the Warthogs' journey forward into the tunnels is blocked off by a Shield Barrier.

If Stacker's on a Warthog with the Chief.


 * Gunnery Sergeant Stacker: "Marines in Voi really needed my supplies, Chief. But I'm pretty sure they'll be plenty happy to see you."

If the Chief waits for a while at the barrier...

or
 * Gunnery Sergeant Stacker: "Take down that barrier Chief. Power Supply should be inside the tunnel."
 * Gunnery Sergeant Stacker: "Chief, the barrier only works against vehicles. You should be able to walk right through."

The Chief walks through the shield, and destroys its power source.


 * Prophet of Truth (broadcast): "“The gods will not begrudge our excavation. By uncovering this relic, we add homage to their glory. When the dust settles, we will all see what I already know: here lies the Path, the start of our Great Journey."

''The Warthogs continue along the Tsavo Highway through the tunnel. When they get out and reach a bridge, a Covenant Cruiser soars ahead.''


 * ONI Recon 111 (COM): "Commander. This is ONI Recon one-eleven. The cruisers above...(static). They found...(static).


 * Commander Keyes (COM): "Say again, Recon? You're breaking up."


 * ONI Recon 111 (COM): "There's something in the crater, Ma'am. Something beneath the storm."

''The Warthogs reach a gap in the bridge and cannot continue. The Master Chief clambers across broken beams and bars and continues on foot. The marines follow.''

The Broken Path
''Wraiths and Choppers'


 * Commander Keyes (COM): "Master Chief? Finally, a good connection. Truth has excavated a Forerunner Artifact, we have to assume it's the Ark."


 * Sergeant Johnson: "Keep pushing to the town of Voi, Chief. Resupply birds will meet you in the next valley."

''The Chief finds Marines pinned down and under heavy fire from Brutes and their allies. The Chief and the Marines eventually clear the sector.''


 * Female Marine: "We've got reinforcements, Marines!"


 * Marine: "Woohoo! Yeah!"


 * Marine: "Booyeah!"


 * Marine: "Ohhhh yeah HAH!!"

A Phantom approaches with reinforcements.


 * Female Marine: "Sir, Recon spotted Covenant armor ahead. Pelicans are inbound with heavy weapons, we need to hold out 'till they arrive."

The Master Chief takes out the Phantom's reinforcements.


 * Marine: "Wraith! Get to cover!"

''A Wraith from further up the trail arrives. The Chief, lacking heavy weapons or ammo for heavy weapons, has to board the Wraith and neutralize it.''


 * Female Marine: "Pelicans coming in."


 * Johnson (COM): "Brutes have plenty of armor between here and Voi Chief, but this Warthog should help you punch on through."

''The Master Chief has a choice of taking one of the Warthogs the Pelicans drop off, or the Wraith that previously attacked if not destroyed. The Tunnel onward on the Tsavo Highway is closed off, so the Chief goes on the trail where the Wraith came from, finding a short tunnel around back onto the Tsavo Highway, but obstructing the way are some Choppers patrolling and soon they are taken out.''

''Nearly a dozen more Choppers, a few Wraiths and Shade turrets defend the route back onto the highway. Despite being greatly outnumbered and out gunned, the Chief and the Marines clear the zone. The Chief takes a look at the massive storm over the vast crater beyond the cliff.''


 * Marine (COM): "Look at the size of that thing, wonder how old it is?"


 * Marine (COM): "Don't know, But I do know that ain't a normal storm."

The Chief observes the cruisers over the crater.


 * ONI Recon 111 (COM): "Commander, I can see most of it now. Readings are all over the EM spectrum."


 * Commander Keyes (COM): "Roger that, Recon. Shut off your gear, fall back. I'll monitor from Kilo 23."

The Chief continues along the Highway.


 * Johnson (COM): "Chief, the gate to Voi is dead ahead. Smash the Brute blockade, open her up!"


 * Prophet of Truth (broadcast): My Dreadnought, the vessel that has so long been the focus of our worship, now rests on it's true pedestal. Even now, it's engines spark greater ones below, relics long without power yet ready to fulfill their divine purpose. Stand fast! Keep our enemies at bay! Soon, my brothers, we will all have our reward!

''The Master Chief goes on foot and encounters heavy defenses by the Brutes, led by a Chieftain. He eventually clears it. The only thing left standing between the UNSC and Voi is another Shield Barrier in the tunnel. The Chief cuts the power source with ease.''

{Cutscene}

Pelicans, including Kilo 23, arrive and drop Warthogs and Marines, Commander Keyes is piloting one of them.


 * Commander Keyes: "Lord Hood? We made it."


 * Admiral Hood (Video COM): "Music to my ears, Commander. What about the Ark?"


 * Miranda Keyes: "Fully uncovered, sir."


 * Admiral Hood (Video COM): "Then we don't have much time. Marines... The Prophet of Truth doesn't know it yet, but he's about to get kicked right off his throne. You will take our city back. And drive our enemy into the grave they've been so happily digging. One final effort is all that remains."

''The Pelicans fly off. The Master Chief draws his MA5C and walks to one of the Warthogs to proceed to retake Voi back from the Covenant.

This is a relatively short level, so it shouldn't be too much of a challenge, especially on Easy. Walk out of the flaming elevator shaft, and look to your right. There are Battle Rifles and Shotguns on racks. You have full BR ammo, so no need for those. Give a Marine a Shotgun and take his AR ammo for your own. Now, turn around and get into a Warthog. The Troop Transport one, preferably, so you can pick up additional Marines along the way. Wait for 3 Marines to get on, and drive. It won't be long before you see some Covenant attacking a group of Marines. Run over some, and let your Marines mop up. Go up the stairs and you'll find another Shotgun for your Marine, meaning more AR ammo for yourself. Since there is no turret on your Warthog it is important to give your Marines a good arsenal. Get back to the Hog and drive out. Ah, the sunshine. So nice to see it again. Run over the Brute, and maybe some other Covenant. Move on, and you'll find two Jackal Snipers. Wipe them out. By now, you should have more AR ammo than BR ammo, so switch your Battle Rifle for a Beam Rifle. Give one to a Marine, and take the other one for yourself. Drive on. Don't stop to kill the enemies, just keep going. You'll hear Stacker making a distress call, and a Warthog should be destroyed by a Chopper right about...now. Kill the enemies, and turn left to destroy the shield. Go through the cave, and come out.

The Broken Path
Don't be afraid of the Cruiser, it won't hurt you. You will come across some enemies. Use your Beam Rifle to snipe some, and clear the area. Take a Brute's Fuel Rod, and fire 4 shots at the Phantom that just arrived in the turbines (the eyes). Make sure you shoot the same eye. Your Rod won't have too much ammo, so give it to a Marine. Take back your snipe. Kill the Wraith, I like using Warthogs better. You could keep it, if you want. Drive through a small cave, annihilate two Brutes and their Choppers, and kill the next group of Covenant. Get back on the road, destroy the roadblock, snipe some Brutes, and break the shield. You're done.

Full Contact Safari
You'll start in an underground cavern after the elevator disaster at the Crow's Nest base. When you start, walk forward a bit, turn right, and go through the door at the end. Open the large door and the far end of the room, and grab which ever Warthog you please. I always take the Troop Transport Warthog. Try playing the level twice, and see which Warthog fits you best.

Once your 'Hog is manned up completely, go through the door. Follow the dimly-lit path, splattering anything in your way. It's especially fun to hit the Brute running up the small hill once you're outside. Turn right up the pathway and splatter anything in your way, once again. You'll soon reach a small area manned by all sorts of Covenant. Splatter all that you can, and continue op the path to the left of the area (it slopes right). You'll get a short message from Sgt. Stacker, and you'll find another large area. Brute Choppers everywhere. Just let your turret (or people in the back) take them out. Then get out, go through the shield door, destroy its core, and head back through.

The Broken Path
When you meet with the Marines holding off the Jiralhanae and Unggoy, a Phantom comes in and drops reinforcements. A Chieftain, a few Jump Pack Jiralhanae and a few normal Brutes. Once they are dead you should grab the Chieftain's Fuel Rod Gun because a Wraith arrives. Once you take out the Wraith you can either wait on Johnson and Commander Keyes to bring in two Warthogs or you can take the Wraith and use it until you get to the cave. There you might want to use a Brute Chopper or the flipped M12 LRV against the back gate. Only if the two Marines are alive is when you should use it. Otherwise you take a Chopper and then you drive down the second to last stretch of highway. There are two Wraiths scattered around the next area. (Three on Legendary) Once you have killed the ten Choppers and the two Wraiths you can drive up the hill to get to the next area which will take you the final area. You can either drive through the first set of Brutes and go to the next or you can kill them. If you're on Legendary it's best to use one of the Wraiths and get a Marine on the turret. You can get up the steep hill and through the barriers by boosting. Once you have killed most of the Jiralhanae you can destroy the Shield Barrier and then you have beaten the level.

Legendary Walkthrough
This level is very easy if done correctly. In the beginning of this level,you should pick your weapons wisely. When you first start out, turn on your flashlights and go to the left. Pick up a Shotgun in replacement of your Assault Rifle. Then, go to the edge of the room to a Marine in pain. One by the door should have a Shotgun laying right next to him. Then, get into the Transport Warthog if on Single play. Along the way on this level, until you make it to the broken path, make sure your Marines take all Fuel Rods and Beam rifles. Drive around and kill all enemies in the doorway and kill all of the next wave that includes a Brute, some Jackals, and some Grunts. Take the Spiker and give it to one Marine (preferably not the one in front).

Next, kill the next two Jackals and take their Beam rifles and give them to the Marines. Continue on until the part with the Plasma cannons. Kill all inhabitants, and take the Brute's Fuel Rod Gun. Give this to the Marine in the front of the Warthog. Then, in the big bowl-shaped fighting area, take you Warthog and park it next to the concrete slabs. A group of Covenant will come up, so take them out with the Marines' help and move it over the deppression. Switch to your Battle Rifle. Snipe the Jackals with the Beam Rifles with your Battle Rifle, there are two on the bridge, and two on the support towers floating in mid-air. Next, snipe the Brutes with Brute Shots with your Battle Rifle if possible. If you don't have enough ammuntiton, pick up the Jackal's Beam rifle and then snipe them. Next, get back into your Warthog and splatter over the remaining Covenant forces. MAKE SURE YOU KILLED ALL BRUTES WITH BRUTE SHOTS, FOR THEY CAN EASILY TEAR YOUR WARTHOG APART!!! pick up a Jackal's full Beam Rifle and give the others to the Marines. Drive to the next part where the Warthog gets run over by the Chopper. Kill the drivers of the Choppers or let the Marines take care of it. Take care of the rest of the Covenant forces. Next, drive up near the part where the Drones attack. When they first come, drive away and let the Marines take care of them. Do this continually until all Drones are dead. Next, Get out of the Warthog and take a Chopper through the next part.

After that, take your Chopper over the next step: The Broken Path. First, ramp over the first broken road segment. Then, take the Chopper and take out any enemies in your way. Kill all enemies and go to the Wraith. Take it out with a grenade, Chopper cannons, or fists. Then, RETURN TO THE FORMER AREA OF FIGHTING. Splatter all Brutes with your Chopper and beware of the Brute Cheiftain. Next, take a Warthog and give the passenger a Fuel Rod Gun. Pick up the Sniper Rifle at the top of the Tower and continue on in the Warthog. In the farther road, drive straight past all enemies. Go through the tunnel and kill the two Brutes next to the Choppers. When you reach the next part of the level, DO NOT STOP MOVING. Take out most of the Choppers before you go near the two Wraiths. After all enemies around are gone, take out the two Shades. On the top of the hill, shoot the gunner off with a Chopper, and melee the driver off. Take the Wraith. Continue on to the small Covenant set-up with Plasma Mortar. Watch out for Jump-pack Brutes for they can board the Wraith. After all enemies in that area are gone, go to the side of the road and pick up a Battle Rifle and Sniper Rifle ammunition. Get back in your Wraith. Fire the Mortar so that the Shade is destroyed. Get out after it is destroyed and use the Sniper rifle to take out any Brutes. When you are out of Sniper Rifle ammuntition, take out your Battle rifle or switch it for a Brute Shot. Take out the remaining Brutes and energy shield. If the level doesn't end and you can't see any Brutes and the shield is offline, search around for the last Brute. They are hard to hear but easy to kill. Congratulations!!! You have finished Tsavo Highway on Legendary and are one step closer to E.O.D. Armor.

Detailed Walkthrough
A brilliant walk through for this level can be found here: http://nikon.bungie.org/gameplay/halo3_slaso/tsavohighway.html

After the detonation of the bomb, Master Chief and several other Marines end up in the basement of the base. The base has sustained incredible damage and the electricity has gone out. If you so desire, you can activate the backup generator (See Trivia, or CTRL+F and look for 'activate'). Don't move around the room until your vision has adjusted, as you may end up walking into a fire, and dying.

Leave the elevator and turn right, so you're facing a weapons rack. Grab a Battle Rifle and fill it with ammunition. Your secondary weapon can either be the default Assault Rifle or you can grab the Shotgun. Turn left again and head into what seems like a garage. You have two Warthogs, a troop transport and a LAAG hog. We are going to grab the LAAG hog for firepower. Wait for your Marines to mount up. Once they do start driving through the caves.

This little bit of the level was probably designed to help newbies learn the general physics of the Warthog. One thing I have learned from experience is that if you are flipping or only on one side, aim to that side. For example, if you are beginning to roll and are currently on your right set of wheels, stop accelerating and aim left. Although counter-intuitive, this will right the Warthog four out of five times. If you are rolling a bit more violently, wait until you slow down, and then perform the above maneuver. Doing this can prevent possibly catastrophic or fatal rollovers.

Alright we're coming up on the end of the cave. You will see a bunch of Grunts and Jackals assaulting some Marines. Give them a hand. Aim for the left or right of the Covenant formation, then quickly turn to the opposite direction. Let's say you aimed for the left side of their formation, they will dive right. By turning right, you actually have them dive into your path. If you do this perfectly, that entire fire team just died. That is the way if you don't know about the e-brake. (the right trigger in the warthog is the horn, the left is the e-brake. If you drive left, hold the e-brake, and point right, you will power slide or drift. This makes crushing enemies a LOT easier. Get out and take the Plasma Grenades. Come out into daylight, you will see a ridge. Gun straight for it, straight down the middle. Upon landing you find a few Brutes, some Grunts, and some Jackals. Your first priority target is the Brute, as it can hijack your hog, and is more likely to stick you. When he is dead the Grunts will panic. Have your gunner mop them up, and aim the hog at the two Jackals up near the hill. Once everything is dead, continue up hill.

You will then encounter two Sniper Jackals. They aren't much, but don't be cocky. They are good shots, and on Legendary, they will most likely one shot kill if you are on-foot. Because a Jackal is good at making a quick dive, chances are you won't be able to splatter them, but the turret on the back will ventilate those Jackals nicely. Swap your long range weapon for the sniper. Give you 'Shotgun' position the Sniper with the least charge. Don't be fooled, the AI is extremely accurate. Continue on to another downed Phantom, the Grunts should have some turrets. The best thing to do is plow the hog right into one, destroying the turret and the Grunt. The gunner will be able to take out the other one. Mop up the panicking Grunts. Stop and get off for the equipment and grenades.

Next you move out into a large area with multiple squads. There will be a Shade Turret, and two squads composed of Grunts and Brutes. Take a left and head towards the first squad. Splatter the Brute and anything else. Once they are eliminated, it's time to take out the turret. Come out from behind the hill where the squad was and locate the turret. Plow straight to the hill its on, and drive full throttle into it. Although this sounds suicide, the Warthog almost always wins, even on Heroic. Once they are dead move out to the other squad and let them taste the dirt. Again, stop for equipment and grenades.

You now move past a blockade thing into a small squad with Carbine Jackals. Once nothing is moving head out down the path to the Tsavo Highway. You encounter some Choppers, your gunner will get them. After, try to save a Chopper. Wait for the Drones to show up before you take out the shield, and stick the Shade when you get a chance. Here is where you would want the Chopper. Get in a Chopper and go the the concrete barrier. If you aim right and boost at the right time, you will drive over the broken path. If not reload and try again. Drive over everyone and kill the Brute with the Fuel Rod Gun. Take his Fuel Rod Gun for the Sniper Rifle. Get back in the Chopper and hide.

A Phantom shows up to ruin your party. You have a Brute with a Fuel Rod Gun as well as a large group of Jump pack Brutes. Wait for the Brute with the Fuel Rod Gun to get in range and drive over his ass. Once everyone is dead add his Fuel Rod ammunition to your own. The Wraith should show up now. Go up to it and melee the driver to death but save the vehicle. Now this is the hard decision. You have a Fuel Rod Gun and need another weapon. I suggest you take the HUMAN Sniper Rifle (at the back of the camp where the Trip Mine is also, don't worry there is more ammo ahead), or the AR (in front of the camp), the BR (same as the sniper), or Shotgun (next to the AR and BR).

Sgt. Johnson now shows up and brings you two Warthogs. However, we are going to drive the Wraith. A gunner should join you and go blast everyone away.

Drive through the cave, you will see two Brutes just standing around. Splatter/blast them. Hop out and look for a Fuel Rod Gun lying on the ground. (keep this gun because sometimes you can start the next level with it) Get in the hog and head to the hardest battle of the level. Ahead there are ten Choppers, two Wraiths and two Shades (varies depending on the difficulty). Drive around down and begin to work at the Choppers. Go left (beware a Chopper will come behind you) and kill everyone. Blast the shades, Choppers, and the Wraiths away with the plasma mortar. Once you get to the road blockade, there should be a pod to your right with a BR and a Sniper Rifle (this is why I told you to get a Sniper Rifle). Take the BR if you don't have a sniper or keep your AR if you have one.

Fire as fast as the Wraith can cycle. Go for total and utter chaos and destruction. Go to the left, and you can get around that first blockade. Again, fire like mad. Take out the Shade as a first priority, the Chieftain is the second priority. If he throws a power drain continue to fire like crazy. If you are under to much fire, make a run for it. once back in the Wraith, simply fire at any movement you see. If you think everything is dead, check your radar. If all is silent, go through the shield, and give the generator a good smack with your melee. Note: If you shoot the generator with the turret from the Chieftain you will not get the weapons you got on The Storm.

Another good way to get through the level is as fast as you can. If you get in the Warthog you can proceed through the entire level in less than ten minutes. You just continue on the Hog until you get to the broken bridge. You can cross this bridge on a Warthog with some difficulty, but it can be done. Use the warthog as a bit of a ram, push a barrier away from the others near it, tipping it over in the process, turn it sideways with the warthog, and push it back against the remaining barriers to become a ramp, position the barrier in the middle of the bridge so it will become a makeshift ramp, if placed against either side your warthog will contact the lights that line the bridge and knock you down, it is necessary to travel back to the dead warthog to begin your run for the jump, if done correctly you can continue on with a warthog. If you do make it continue past where the first wraith and phantom are through the caves. Then you come to the most difficult part of the level. From here you have to destroy the two choppers, then hijack one Wraith and destroy the other. After this you can just continue down the road in the wraith until you reach the final battle. Once you get here clear out the enemies with the wraith, then you have to get out of your vehicle and destroy the shield door, then the level is complete. This way isn't exactly "completing" the level, but you still get the achievement and is really easy.

Achievement Help
We're in for some Chop: Towards the start of the level, you will get to the area with 2 choppers and the first shield door. As you enter this area, towards the right will be a few small huts. Inside these are trip mines, which are pretty much the only type of equipment capable of getting the achievement. Go out to the Choppers, and get one to follow you. As its coming towards you, throw down the trip mine in front of it, and it should destroy it. It may help to damage it with gun attacks as well so that it has no chance of surviving the impact.

Glitches

 * In the beginning of level, if the player goes to where the Marine is turning on the power, there is a switch. When approached, the switch will move down. However, when the player moves away, it will go back up. The switch does not do anything.
 * On the stretch of road with the Pipe running adjacent to it, if you are in a Warthog and you stop at a certain place so that a metal, curled post is above you, your Warthog will turn black.
 * If you look at where the CCS-Battle Cruiser appears from the cliff after the Drone ambush, a glitch will happen where you will see the side of the cruiser before the ship actually appears.
 * Sometimes, Sergeant Stacker's character model will appear instead of Sergeant Reynolds, however all scripted dialogue will remain unchanged. Oddly, even after both sergeants are together, Reynold's voice will still come from Stacker's model, and vice-versa.
 * It is possible to jump the gap in the bridge with a vehicle if you have a Gravity Lift handy. This can also be done by knocking down a barrier and pushing it around with a warthog until it turns into a makeshift ramp, although this is slightly time consuming. An easier way to cross the gap is by bringing your chopper as far forward as you can without falling off and then boosting.

Mistakes

 * In an article on IGN, it is said that Cortana's voice-over tells you about the stranded transport team. However, it is actually the voice of Miranda Keyes, whose new voice actor sounds similar to Cortana.
 * At the beginning of the level, if you look at the medic treating the injured marine, he will occasionally click on a data pad in his hand. However there is no data pad to click on.

Easter Eggs

 * It is possible to find more sniper ammo in the area after the destroyed bridge where you are forced to dismount, climb the hill to the left of the area to get to the top of the structure and there is a dead marine with a sniper rifle.
 * The Tough Luck Skull is found on this level.
 * At the very start of the level if you look at one of the walls you can see the word "hi". verification needed
 * The two cave doors in the beginning of the level are both door number 7. Another 7 reference.
 * Tsavo is notable in that it was the site of the most famous instance of man eating lion attacks in the late 19th century as detailed in the book "Man-Eaters of Tsavo." More than 140 workers perished in the building of the railway. The event was made into the film The Ghost and the Darkness.
 * The Marathon logo is visible on the side of the CCS-Battle cruiser that passes overhead.
 * In the campaign lobby, Mission Start is labeled as "Warning: Hitchhikers may have jet packs". However, no Jump Pack Brutes appear before Rally Point Alpha. This is also a reference to the last chapter name in the Halo: CE level The Maw: "Warning: Hitchhikers May Be Escaping Convicts."
 * Admiral Hood says at the end of the level "One final effort is all that remains". The Prophet of Truth says this on the speakers in the Halo 2 level High Charity. This is also the name of a song in the Halo 3 Original Soundtrack.
 * If you look on all the signs in which it says the distance to Voi and New Mombassa. It will always say that Voi is 17km away and New Mombasa is 124km away. Same for the opposite direction. The distance to New Mombasa is a seven reference: 1+2+4=7.

Miscellaneous

 * The Brute Chieftain with a Gravity hammer does not appear in this level.
 * It is possible to carry over into the beginning of the next level (The Storm) whatever weapons and ammo you retain from the end of this level sans sniper rifles (e.g., battle rifle and plasma cannon).
 * This level, along with The Covenant and The Storm, are the only three levels you can drive a Transport Warthog.
 * Tsavo is a region of Kenya close to where the Tsavo and Athi rivers meet and was the place where the Uganda Railway passed over the Tsavo river. The bridge will not be encountered as it is on the other side of Voi.
 * It is the first Halo 3 campaign mission to feature usable vehicles.
 * Scattered across the land are the remains of the New Mombasa Orbital Elevator. It collapsed after New Mombasa was "glassed", and not by the slipspace rift created when The Prophet of Regret's ship fled the city on October 20th, 2552.
 * There is a weapons cache on top of the tunnel in the first area where the Pelican drops off two Warthogs, but if you enter it, the Wraith will bombard you from a distance.
 * Near the end of the level, you can see the ruins of New Mombasa in the distance near the edge of the crater.
 * This is the only level where Thel 'Vadam is never seen in single player Campaign mode. This is probably because he, in Bungie canon, had been evacuated from the Crow's Nest via Landing Pad Bravo when the Brutes disarmed the bomb.
 * This is the first level you can see a Wraith in Halo 3.
 * At Bungie's Halo 3 preview event in Seattle, Washington (Close to where Bungie Studios is actually located on the map) Tsavo Highway was first shown to the groups that attended the event's meeting.
 * In the Halo 3 Epsilon, no static effects were added to dialogue. It was possible to hear the complete transmissions from Stacker and ONI Recon 111 respectively: "We're on the Tsavo Highway, about five clicks east of Voi." and "The cruisers above the crater. They found something."
 * This is the only level in Halo 3 where John-117 has no dialogue in the cutscenes related to the level.
 * Before heading to the garage in the beginning of the level, you can go to the doorway opposite of the garage entrance and reactivate the entire bases' backup power supply from there by pulling a lever in the room.
 * This level along with The Ark and Halo are one of the only levels to not feature any Cortana/Gravemind moments. However, Halo does feature a Gravemind moment instead.
 * This is the first level in the trilogy where the Brute Chopper comes in.
 * After taking down the first shield generator and moving through the tunnel, there is a marine outpost with a single dead marine. This outpost has a fully charged Plasma Rifle outside that is unaffected by the Famine Skull.
 * This, the Ark, and the Covenant are the only levels to have Beam Rifles by default on any difficulty.
 * Tsavo Highway was originally split into two separate missions. They were merged into the current iteration due to production schedules.
 * Where you first see the choppers there is a hidden dialogue from Gunnery Sergeant Stacker saying "bitch started jumpin', strippin' down, pretty much ruined our day"
