== Level Start ==
This is a walkthrough for the Level [[ONI Alpha Site (Level)|ONI Alpha Site]].   It is written for play on [[Legendary]] difficulty and has notes for lower difficulties. 
Dutch and Mickey got attacked with heavy fire from the Covenant. The only way they can save themselves is to blow up the bridge and run…


You enter Dutch's vision, and Mickey will ask you to arm the charges. Each charge is found on a pillar. Simply get to them and press RB to arm them. Get off of the bridge and climb on the tower with a sniper rifle. Press the controls (press RB) and blow the bridge up. There should be no survivors. Although, sometimes 2 wraiths will survive on the piece of land at the beginning of the bridge, so watch out for those. You can make sure they don’t survive by shooting them with one Spartan Laser shot each; but make sure you have 2 laser shots for the Hunters in the next area.


== Behind the Walls ==
Dutch and Mickey fell back to the line, only knowing that taking out the bridge wasn't enough because the Covenant sent Phantoms behind them, attempting to breach their base…


The Phantoms drop down a [[Hunter]] pair, Grunts and Brutes. A [[Spartan Laser]] can instantly kill a Hunter with a direct hit in the gaps between their armor, or if you took the sniper rifle before, snipe it in the gaps of armor in its back or head. Staying on higher grounds would help in Legendary, so make sure that once you take out the Hunters to quickly get up the hill. Get across the fields and regroup with the NMPDs. Then hold the position until a NMPD screams fall back. Take the turret if you want; but be quick. Using the turrets up there without detaching them could mean you will die because the Wraiths will fire at the walls, killing you instantly on [[Legendary]], so it would be better if you quickly detach a turret and use it to fight off the brutes and grunts on the hill. Now go down to the gates, and you will find a rocket launcher. Pick it up and use it, and give it to Mickey before finishing off all the rockets. Since ODSTs cannot die, giving them powerful weapons would make them really strong and help you on lots of killing. Grab a turret or something and start the massacre!
This is the second mission that you play as [[Taylor H. Miles|Dutch]], with [[Michael Crespo|Mickey]] as your ally.  This mission is one big firefight.  Your starting weapons are the [[Weapon/Anti-Vehicle Model 6 Grindell/Galileian Nonlinear Rifle|Spartan Laser]] and the [[M7S Caseless Submachine Gun|SMG]].  There is no subtlety or sneakiness to this level.  You cannot avoid the enemy in any part of the game, so knowing your weapons, their capabilities and how to best use your [[Non-Playable Character|NPCs]] is really important.  There are no "good" Skulls for this mission, but Black Eye, Tilt and Mythic  will make this level feel nearly impossible to beat and incredible when you do.


== ONI Base Interior ==
Dutch and Mickey tried to hold back the Covenant forces, but they fall back due to the overwhelming forces…


A turret is in the middle. Grab the turret without detaching it. Make sure you are ready because once the Covenant start coming in, they won’t stop. It will be like a shooting gallery, having you switch from the left doors and the right doors. The first wave would be lots of Suicidal Grunts. Having the turret can kill them easily. The second wave would still be lots of Grunts and a few shielded Jackals. In Legendary, you may want to stop, as the third wave with Brutes would be coming. Since they wield Brute Shots, using the turret would be a problem. But it's okay if you have nice aiming or you're not playing on Legendary. Behind the lines, a Phantom flies by and drops off a couple Brutes with brute shots and brute plasma rifles. Detach the turret (if it's still intact) and start the killing. As long as the brutes get killed, you’re fine. Waste them and Mickey will ask you to get to his position, which is at the elevator in the previous room.


== Up the Lift ==
Dutch and Mickey met a surviving NMPD officer in the lift, and together they go up to the rooftop…


 Drones will appear and start shooting at you. Take cover behind the door of the lift, and pop up to shoot the drones whenever you feel like it. But it would be best to save your ammo for the following fight. This would be a smart thing to do on Legendary because after you come off the lift, it will leave you with almost no cover whatsoever on the rooftop. Once you get to the top and the doors open, get ready.  
== Boom Goes the Dynamite!!! (Or, Why I love my job!) ==
As you start this mission, you're running away from the Covenant.  Get used to it, most of this mission is running away.  Arm the charges, then head for the left hand tower and set them off, blowing the bridge and killing everything.  You can run around shooting at enemies and eventually Mickey will detonate the charges, but on Legendary, you can't afford to waste the ammo.  Head over to one of the [[M68 Gauss Cannon|Gauss turrets]], and take out the [[Type-25 Assault Gun Carriage|Wraith]] on the other end of the bridge, you'll end up shooting a few [[Type-26 Ground Support Aircraft|Banshees]] too.  You could skip this, but occasionally some Wraith Plasma will make it over the wall.  Don't risk it, take a few seconds and clear your enemies.  Once done, head under the wall with Mickey.


== Extraction Point ==
== You Wanna Piece of This!!  (Or, Come get Some!) ==
Dutch and Mickey fought the Drones all the way up to the roof. But they won’t get out of this easily…
Under the wall, Melee the [[Kig-Yar|Jackals]] before heading out.  Bring up the Spartan Laser and quickly dispatch the two [[Mgalekgolo|Hunters]].  If you're lucky a few others will stray into the beam.  Start running.  head towards the building shooting and tossing grenades.  It will give you a little relief when you're running to the shelters.  Once on the first tier, swap your SMG for a [[MA5B ICWS Assault Rifle|MA5C]].  There's plenty around and on legendary difficulty there will be plenty of dead Marines to get ammo from.  The MA5C is better at close range than the SMG and has a better melee.  On lower difficulties, stick to the SMG, the Marines are heartier and won't die so you can't get more ammo, plus the SMG deals death pretty well on lower difficulties.  As you withdraw, use lots of grenades if you have them, and you should there are plenty around.  Once you're at the top, stay away from the [[AIE-486H Heavy Machine Gun|turrets]] as getting behind a stationary emplacement at this point is instant death, run down the stairs, grab the [[M41 SSR MAV/AW Rocket Launcher|Rocket Launcher]] and Swap with Mickey.  He'll do a lot more damage with that than the SMG.  Run back and Grab your Spartan Laser.  There seem to be three ways to trigger the recall into the building. 1) Run around killing indiscriminately until a certain amount of time has passed, 2)  Kill the [[Brute Chieftain|Chieftain]] with the [[Type-2 Energy Weapon/Hammer|Gravity Hammer]] (this one is really hard so don't bother unless you're really sure you can get at him) or 3) kill the Wraiths.  If you're playing on Legendary, you should be able to kill a Wraith with One shot from a Spartan Laser.  Do the one on the left first, then run to the right and kill the second one.  This should trigger the recall.  Before you run in, On the ground on the right side in back there's another full Laser, grab it.  And if you think you can get away with it, grab a turret too.  Head inside.


 Now you made it. Get off the lift and find yourself outside. Once up, there are lots of Jump Pack Brutes and a Gravity Hammer wielding War-Chieftain. The NMPD officer usually won't make it here. On Legendary, it takes about four shots from a Spartan Laser to kill the Chieftain, but less if you gave Mickey a Rocket launcher. Kill the Brutes out there and an NMPD Pelican will arrive. Getting on it will end the level and show the Post-Game Carnage.
== Bring the Rain!!! (Or, Lead Showers and Bloody Flowers) ==
 
Once your inside head over to the center and drop your second turret towards the back stairs, it will be safe there and you can come back for it later.  Take your place at the second turret.  Follow the directions of Mickey and the NMPD officer, but don't be beholden to them keep sweeping left and right.  You can kill the [[Unggoy|Kamikaze Grunts]] and Jackals, but watch out for the [[Jiralhanae|Brutes]] with [[Type-25 Grenade Launcher|Brute Shots]].  Hop off the turret, and wade into the fray, using Grenades and your Assault rifle.  The Brutes seem to focus on the center, so if you stay to the top you can get behind and assassin melee from behind.  This isn't foolproof though so stay on Guard.  Between Mickey and Yourself you should be able to end the frontal assault quickly.  Next grab one of your turrets and watch for the phantom to drop it's force behind you.  Use the turret to clear the Brutes and then finish it with your MA5C, taking out the Jackals and Grunts.  Mickey's rockets will do plenty of damage to help you out.  Once your done, load up with a Brute Shot for your MA5C, your full Spartan Laser and the other turret.  Grab any grenades you can find and head into the elevator.
== Quick Tips ==


== Enjoy a Firefight on Our Beautiful Rooftop Patio.. ==
Before you start the elevator, drop your turret and swap your brute shot for the NMPD officer's MA5C.  Pick up the turret (otherwise it has been known to disappear). and activate the elevator.  Drop the turret near the door and stay clear of Mickey and the cop as they shoot their rockets and grenades at the [[Yanme'e|Drones]], clean up what they miss.  As you reach the top, switch back for the Brute shot and pick up the turret.  The heavy weapons will make short work of the jump Brutes here and you can then focus on the Chieftain.  between your laser and Mickey's rockets, he won't last very long.  Hop on the [[D77C-NMPD Pelican Dropship|Pelican]] and watch the fireworks.........

*Blowing up the [[Banshees]] and [[Wraiths]] on the bridge would cause Mickey to activate the charges and shows dissatisfaction.
*On the bridge, you get two kills if you shoot down a Banshee with the Spartan Laser and three kills if you shoot down the Wraiths. There are two Banshees and three Wraiths that would make getting the achievement easier.
*There is a hidden Rocket launcher near the gates of the ONI Base.

Revision as of 09:47, October 26, 2009

This is a walkthrough for the Level ONI Alpha Site.   It is written for play on Legendary difficulty and has notes for lower difficulties. 


This is the second mission that you play as Dutch, with Mickey as your ally.  This mission is one big firefight.  Your starting weapons are the Spartan Laser and the SMG.  There is no subtlety or sneakiness to this level.  You cannot avoid the enemy in any part of the game, so knowing your weapons, their capabilities and how to best use your NPCs is really important.  There are no "good" Skulls for this mission, but Black Eye, Tilt and Mythic  will make this level feel nearly impossible to beat and incredible when you do.



Boom Goes the Dynamite!!! (Or, Why I love my job!)

As you start this mission, you're running away from the Covenant.  Get used to it, most of this mission is running away.  Arm the charges, then head for the left hand tower and set them off, blowing the bridge and killing everything.  You can run around shooting at enemies and eventually Mickey will detonate the charges, but on Legendary, you can't afford to waste the ammo.  Head over to one of the Gauss turrets, and take out the Wraith on the other end of the bridge, you'll end up shooting a few Banshees too.  You could skip this, but occasionally some Wraith Plasma will make it over the wall.  Don't risk it, take a few seconds and clear your enemies.  Once done, head under the wall with Mickey.

You Wanna Piece of This!!  (Or, Come get Some!)

Under the wall, Melee the Jackals before heading out.  Bring up the Spartan Laser and quickly dispatch the two Hunters.  If you're lucky a few others will stray into the beam.  Start running.  head towards the building shooting and tossing grenades.  It will give you a little relief when you're running to the shelters.  Once on the first tier, swap your SMG for a MA5C.  There's plenty around and on legendary difficulty there will be plenty of dead Marines to get ammo from.  The MA5C is better at close range than the SMG and has a better melee.  On lower difficulties, stick to the SMG, the Marines are heartier and won't die so you can't get more ammo, plus the SMG deals death pretty well on lower difficulties.  As you withdraw, use lots of grenades if you have them, and you should there are plenty around.  Once you're at the top, stay away from the turrets as getting behind a stationary emplacement at this point is instant death, run down the stairs, grab the Rocket Launcher and Swap with Mickey.  He'll do a lot more damage with that than the SMG.  Run back and Grab your Spartan Laser.  There seem to be three ways to trigger the recall into the building. 1) Run around killing indiscriminately until a certain amount of time has passed, 2)  Kill the Chieftain with the Gravity Hammer (this one is really hard so don't bother unless you're really sure you can get at him) or 3) kill the Wraiths.  If you're playing on Legendary, you should be able to kill a Wraith with One shot from a Spartan Laser.  Do the one on the left first, then run to the right and kill the second one.  This should trigger the recall.  Before you run in, On the ground on the right side in back there's another full Laser, grab it.  And if you think you can get away with it, grab a turret too.  Head inside.

Enjoy a Firefight on Our Beautiful Rooftop Patio..

Before you start the elevator, drop your turret and swap your brute shot for the NMPD officer's MA5C.  Pick up the turret (otherwise it has been known to disappear). and activate the elevator.  Drop the turret near the door and stay clear of Mickey and the cop as they shoot their rockets and grenades at the Drones, clean up what they miss.  As you reach the top, switch back for the Brute shot and pick up the turret.  The heavy weapons will make short work of the jump Brutes here and you can then focus on the Chieftain.  between your laser and Mickey's rockets, he won't last very long.  Hop on the Pelican and watch the fireworks.........

Notes

  • Using the Machine Gun Turret inside the building without detaching it is a good idea. Just detach it once the brutes come in to take out their shields, then go in for the kill.
    • Another good idea is to kill the grunts and jackals in the area. Then, once the Brutes come, run to the back of the room and stay in the doorway there. The Brutes will almost never go back there to fight you, except maybe more frequently on Legendary. Just make sure you don't get shot from them when they are away from you.
  • Don't take out the banshees at the bridge part with your Spartan Laser. Those banshees hardly ever harm you, and the laser shots you use on them would be a waste, as you need them for the next section
  • On the way up the lift, hide behind the door/glass section, if  you don't want to get shot by the drones
  • On the roof, give Mickey the tough weapons (e.g., Rocket Launcher, Spartan Laser if you still have it and the Machine Gun, if you still have it) and hide inside where the lift exit is. That way you won't have to fight as much.
  • When the enemies start flooding into the building when you are in the middle with your team, make sure you switch from left to right and back again. If you continue to shoot and throw grenades at one side without caring about the other side, you will probably lose a lot of health and die.
  • Since ODSTs cannot die, giving them powerful weapons would make them really strong and help you on lots of killing.

Taking out the enemies before blowing up the bridge will gain you a Killing Frenzy or higher.
The banshees are not that much of a threat, but you can take them out anyways.
Be careful about taking out the Chieftan on all difficulties!
