Valhalla

Valhalla is a multiplayer map in Halo 3. A from-the-ground-up level, it is said to be "A spinoff of the Blood Gulch map from Halo: Combat Evolved". The map is a sparsely forested valley with mountains in the distance, featuring a river, rocky outcroppings, a large reduction in size, and hills. Bungie added these new land features to help balance the action between snipers and on-foot travelers, whereas in and Coagulation, those players were easy prey. These minor alterations cause drastic changes in gameplay. Some have said this was somewhat of a replacement for Blood Gulch and.

In a FAQ of Halo 3 Beta, Bungie has replied to the question "Why is there no Halo in the sky above Valhalla and Snowbound?", by saying "Who said Valhalla is anywhere near a Halo? The Galaxy is a big place, and there are only six Halos left." The FAQ can be seen here. The map is quite large. It has a canyon with hills, lots of trees, cliffs, a very large Forerunner wall on one side, and a river running through.

Overview
The map is similar in shape to Blood Gulch but has unique elements of its own. Valhalla is not a remake of Coagulation, nor is the downloadable either. Valhalla also has features from the Halo: Combat Evolved level; Halo. The most obvious feature is both the river and the bases themselves. The river starts in the mountains behind blue base, and comes out at a waterfall. The river then flows in front of the base, under an outcrop, then down between the two prominent hills on which players find the Spartan Laser, and the AIE-486H Heavy Machine Gun. Finally it bends around the base, and empties into a large lake. Also, there are two other caves in the map, one which goes through the hill between the crashed Pelican and blue base and the other which goes through the hill between the Pelican and red base. Do note that if weapons are dropped into the river, they might drift downstream.

The distinguished beam emitter bases are Forerunner technology. They are similar to the structures seen in the Halo PC multiplayer map Infinity, Timberland and in the campaign level Halo, while the lower portion is reminiscent of the bases in Blood Gulch. There are three entrances to the inside of the base; two on the sides as seen in many screenshots, and another located behind that dips down into the base. Replacing the teleporters are the Man Cannons. The largest one, on the front of the base, will send you out a third of the way out into the main battle area, while the smaller ones on the side of each base send you a short distance to the nearby cliff for a quick getaway. The bases feature a shiny glass floor on the interior, allowing players to see who is above them and vice versa.

As previously stated, there are two similar hills on either side of the river. On one, the highest, spawns the Spartan Laser, while the lower hill holds an AIE-486H Heavy Machine Gun. Each base holds a Sniper Rifle inside the rear entrance, a pair of Fragmentation Grenades and Plasma Grenades. Numerous Battle Rifles spawn around the map: two on top of the base next to the smaller Man Cannons, two underneath the base alongside each entrance along with two Plasma Pistols, two on the terrain where you land after taking off from the Man Cannons, and one that spawn in each cave. A Shotgun spawns inside each of the caves as well, and Spikers spawn on the top of both bases near the Missile Pod. A pair SMGs also spawn on each base and are located next to the Plasma Grenades. Valhalla is a very good sniper map since you can snipe opponents clear to the other side of the map, and when players take the Bases Man Cannons for rapid transportation, they become easy targets for Snipers.

The Missile Pod spawns on top of each base to provide initial anti-vehicle defense. The current vehicle set per base is a Banshee, Warthog, Wraith, and two Mongooses. However, in the Matchmaking playlists the vehicles are limited to a Warthog, a pair of Mongooses, and a Banshee per base (in 4v4 matches, most notably in Team BRs, the Banshee is sometimes removed). The Power Drain spawns on top of each base next to the Missile Pod, while the Bubble Shield spawns at the neutral Mongoose near the Forerunner wall.

Like the Halo Installations, the planet is populated by a mixture of flora and fauna, some unique and others peculiarly similar to Earth classes, and as mentioned before the bases are Forerunner energy stations.

Valhalla Heavy

 * An additional Warthog spawns alongside the default Warthog spawn at each base.
 * A Scorpion Tank spawns in front of each base.
 * A Spartan Laser spawns alongside the default Sniper Rifle spawn point at each base, another spawns at the Pelican site, and another at the Turret site.
 * An additional Bubble Shield replaces the Regenerator spawn at the Pelican site.
 * Teleporters are added to the map. Each base's lower deck has a Sender Node Teleporter which teleports players to other Receiver Node Teleporters either near the Pelican side or the Turret site, functioning similarly to Blood Gulch's and Coagulation's teleporters.
 * The formerly default Spartan Laser spawn has been replaced by a Rocket Launcher.

Strategies

 * Use the Banshee when the Spartan Laser is in your control.
 * A good strategy in Assault is to secure the enemy base and the bomb spawn. Simply bring the bomb over to the base, plant it and camp with shotguns to protect it. Have a player stay near the spawn to pick it up and repeat this process.
 * The Banshee can make a great hit and run aircraft as it can fly in on the enemy base fire, then turn round the tower then head back, turn round at the friendly base for another attack run.
 * A good trick is to use the man cannon while driving the mongoose then jumping off, as it will not go as far as the player. This will confuse the enemy firing at the empty mongoose, so that the player can flank them. Only players who look closely will realize that the driver has jumped off.
 * For a Team based game, it is imperative to control the Spartan Laser and the ground around it. The Laser allows your team to fire upon the enemy base from a distance, or kill them coming down from the Man Cannon, stopping them from being able to fight with a little breathing space. However, sometimes a mad rush for the Spartan Laser leaves your base open.
 * When piloting the Banshee, it is advantageous to fly low and strafe at the higher Banshee. The pilot will have to turn around giving you more than enough time to disable it or destroy it, although this leaves you open to being hijacked, lasered or locked on.
 * If you can, try stealing the enemy's banshee. With your Banshee and your captured ones, you will have control of air support. This works better with Warthogs, allowing you to flank enemies trying to escape the Warthogs.
 * While the central hill does provide an excellent view of the map, be aware that this makes you a target for snipers.
 * Try not to use the Spartan Laser on lone targets such as one person charging the hill with no back up, rather save the charge for higher-priority targets, such as incoming vehicles or a player wielding a Missile Pod.
 * If you have the flag, unpredictability is key to survival, especially if the opposing team has the Spartan Laser - one deception or erratic movement is often the difference between victory and defeat.
 * Since this map has many hills and corners, tanks are better off on defensive backed up in the corner
 * Try to secure the Spartan Laser first and foremost to allow you to take out infantry and vehicles with ease, if you're on defense fall back to the base and use it on assaulting vehicles, using a Battle Rifle or similar to take out distant-enemies before they reach the base. If on you're on offense, use the Spartan Laser to cover the rest of your team, then you should to help retrieve the flag or protect the bomb from being disarmed.
 * When a bomb is planted, bring a regenerator to increase your durability from grenades and power drains that are often tossed inside.
 * Have your VIP stay inside the lower level in the base and jam the center with the warthog. Have the shotgun wielder cover one entrance and the SMG wielder cover the other. Always have some sort of support when doing this(Bubble Shield, Regenerator) Have another player man the warthog turret and the banshee pilot impede the enemy's advance. Be sure to have a few teammates watching the base from somewhere else. Some players have commented this strategy has almost no weaknesses.
 * The initial rush straight for the Laser once the game starts can be swung your way by throwing grenades to land just beyond the lasers spawn point knocking down shields or even killing members of the other team with the same objective in mind. Throwing a Power Drain is also wise.
 * Be extremely careful while driving a Banshee, if you swerve off too late while strafing it could cost you the vehicle.
 * Try sniping in less commonly used areas, like right behind the turret where players think a sniper would never venture.
 * For territories sticking together is the best way to win, usually, an offensive team will stay in one large group moving from territory to territory, making it hard for a team to defend all of the territory's at once, so for defense, move up to the bases that will be easiest for the attackers to capture (The crashed pelican, the shotgun spawning points) and try to protect those with a larger group, and keep a few of the back ready to move to another territory while the rest deal with other attackers.
 * As a note, Territory 4 is a very dangerous Territory due to the fact it is in a cave, and multiple grenades can be thrown in to kill the attacking force. Try to always bring a Bubble Shield and/or Regenerator.
 * If your flag gets stolen, guard the primary man cannon, that is where the carrier is most likely to go after he/she steals the flag
 * An interesting tactic to do on CTF is to drop it on top of the fusion core at the stump on the base and shoot it. This will launch the flag at least halfway across the map, making the trip a lot less hectic.
 * The crashed Pelican provides a great place to snipe since the player has a decent view of both bases. It is also recommended because of a regenerator that spawns under the wing should the sniper be in trouble.
 * You can have your VIP jump on your Banshee and move it to the top of the base where the VIP has a vantage point. Although the VIP is prone to the laser and its lethal range.
 * As in any Team Slayer game, move as a pack, and do not get separated. Controlling the Spartan Laser and the Missile Pods are the key to this level because vehicles will not have to worry about getting destroyed so easily.
 * If you are in the Coastal Base and you use the Man Cannon, you can actually jump across the river from where you land, with at least some momentum left from your launch. You must land pretty much on the edge of the land before you would fall into the river, if this can be done right, it may be helpful to get closer to the Spartan Laser on the hill.
 * Try to use the Warthog when taking out enemies on the hill, especially if they have a Spartan Laser and are trying to kill a teammate of yours in a Banshee as they won't focus on you as much.
 * Rushing for the Spartan Laser is wise ecpecially if you have a Warthog and a Banshee on the offensive. The center should be secure, but the outskirts will be unprotected and enemy warthogs and banshees will be already firing.
 * At the start of the game, if you are going for the Spartan Laser, pick up the Power Drain and throw it as you man cannon towards the hill, this should deter, weaken, or at least hold back the enemies while you pick up the Laser, and also have a Sniper in the base and/or other players to protect as you get to a safe distance with the Spartan Laser.
 * A good Sniper tactic in Valhalla, is to jump as you approach the Spartan Laser hill. Even if you don't have a good aim, you can still badly injure a few of the other team, making the Spartan Laser easy to claim.
 * Go to the pelican with a sniper and you can kill anyone trying to grab the laser. You can delay them until your team has possession of the laser.
 * A good sniper place is to get the Sniper Rifle and Banshee and ride up to the top of the base. If you do it correctly you will be able to snipe people with in the whole map. But remember to look out for the mortar that the bases fire. Another way to get there is by positioning a Wraith beside the back entrance of a base, and jumping on top of it. Then, jump up to the slippery platform. What sure you keep jumping forward until you reach the location. This tactic is harder and can also be done with a Warthog or by Team Jumping/butterflying.
 * In CTF or Assault, have someone camp with the Missile Pod. It can destroy incoming vehicles, or at close-med ranges, it can be use as a compensation of a Rocket Launcher.
 * The Missile Pod is surprisingly effective inside the lower area of the base.
 * In CTF, if you manage to kill the carrier in a wraith, park it on top and destroy it just melee the back engine a few times, this makes it underneath the wreckage and nearly impossible to retrieve, depending on your parking job. Be careful if you stand too close, the flag will respawn at your base. The wreckage does disappear after a while, however.
 * A stealthy player can sneak over the side of the center hill, he can be virtually invisible or spotted before he even reaches there. It all depends on who is attentive and who's watching their sensor.
 * Sometimes, some weapons will float down the river, players can pick up Shotguns, Spartan Lasers and even missile pods or extra ammo.
 * An excellent defense base is having a wraith guarding the outside and having a player sniping from a nearby ledge. It can be more solid if you have a few players armed with SMGs or shotgun.
 * The Plasma Grenades and Battle Rifles have a fast respawn time on each base. Unless the need to move out is urgent, it's usually worthwhile to wait for them.
 * The caves are notorious for having campers with shotguns inside. Unless the other routes to the enemy base is guarded throw a few grenades and flank, where the camper will fall back, causing you to catch him off guard.
 * The Power Drain should be useful when numerous foes are arriving at the arming spot or Flag in Assault and CTF games. Just hold your nerve and deploy it when you've almost touched their objective.
 * A defensive player should move to the caves and grab a shotgun to use in the basement floor of the base.
 * When using a Power Drain and Man Cannon, please note that the Power Drain will not reach the hill if thrown in the Man Cannon, it's a common mistake and can be rectified if you yourself use the Man Cannon and fling the Power Drain while in 'flight'.
 * The Pelican is notorious in territories for the regenerator and close proximity to territory 4 and the Spartan Laser, the only practical way to deal with this territory is to control the hill and maybe save a Power Drain to cancel the regenerator's effects.
 * The rock laying on its side near the waterfall base can serve as an outpost. A sniper can crouch there and eliminate anybody heading that way.
 * Another good tactic is to grab the Missile Pod at the start of the match. This is because somebody on the other team often gets in the Banshee. The Missile Pod can easily destroy the enemy Banshee, which can be a real advantage.

Trivia

 * Valhalla (Old Norse Valhalla, "Hall of the Slain") is Odin's hall of the dead in Norse mythology, the home of those slain gloriously in battle. It is similar to MJOLNIR, as they are both of the same mythological origin. Interestingly, Valhalla was home to dead warriors that rose with the sun, every day, to fight each other and enjoy the thrill of battle, and during the night they had great feasts and healed their wounds. This is remarkably similar to multiplayer gameplay.
 * The two towers on Valhalla show a striking resemblance to the towers in the level Halo on Halo: Combat Evolved.
 * Like the Halo 2 map, there is writing on the wall that changes according to the date.
 * The D-77 TC Pelican Drop ship Victor 398 mentioned in the map description can be seen to have crashed along the shadowed cliff between the bases. Weapons canisters from the drop ship appear to be scattered across the battlefield.
 * The map's general layout and design bears a startling resemblance to the level Halo in the first game, and may have been inspired by it, as well as incorporating elements from Blood Gulch/Coagulation and Timberland, a similar map from Halo:PC.
 * This map was named "Riverworld" and then "Curious Gorge" before Bungie finally settled on "Valhalla".
 * In the Halo 3 beta, you could fly into outer space in a Banshee by exploiting a glitch.
 * You can fly to the top of the towers using a Banshee and then wait for a few minutes before being killed by the Guardians (the laser fires up and hits you).
 * During the Halo 3 Beta, each base spawned a Trip Mine. Unfortunately, due to players' inexperience with equipment, using it as an ambush for unwary enemy team members often resulted in the deaths of those friendly units still around it, and so it was removed from the final game.
 * During the concept of this map, Bungie intended to make the map more of a snowy map than a forest one. Because of Snowbound, Bungie decided to make a forest map instead. However, some snow can still be seen near the base located near the waterfall. There is also snow atop the cliffs surrounding the majority of the map.
 * The river that runs through the center of the map has a fully functional current. A light enough object, or a dead Spartan, will flow down the river from the waterfall towards the lake. If the object floats far enough in the lake, it will drop underwater when it reaches the "death border".
 * Butterflies can be seen near the weapon canister opposite the Pelican.
 * Looking closely at the edge of the platform where the Banshee spawns, you can see that the texture of the metal resembles the face of Ling Ling, Bungie's dog.
 * There are dim lights inside each of the bases, giving the room a red or blue ambiance. However, the default and matchmaking spawn points in team games (CTF, Assault etc) spawn red team in the Blue Base (Lake Base) and blue team in the Red Base (Waterfall Base).
 * Each base seems to be a large Forerunner Beacon identified by the long stretching tower and edifice streaming wayward plasma beams firing into the sky, as seen in the Halo: Combat Evolved campaign mission, Halo.
 * One mountain across the water looks similar to the mountain in the background of Snowbound.
 * It was possible to place the flag on the fusion cores next to the man-cannons and then shoot the coil sending the flag clear across the map, even directly into your own base. On August 2009, Bungie removed those two fusion coils from the default and heavy variations of Valhalla, presumably for this reason.
 * There is a ghost in Valhalla.
