Beaver Creek

Beaver Creek is a multiplayer level from Halo 2. It is set in a tiny canyon featuring two symmetrical bases that are separated by a small creek. Beaver Creek is a remake of the map Battle Creek from Halo: Combat Evolved, and was remade as Battle Canyon for Halo: Combat Evolved Anniversary.

Summary
Significant changes from Battle Creek include, breakable glass roofs on the bases and ramps instead of ladders leading to the Sniper Rifle and Magnum, which replaces the second Sniper Rifle. Two bases lie on opposite sides of this small map, separated by a small stream. Above the stream a giant rock walkway leads to a Rocket Launcher.

On the left side of each base a path leads to the upper portion of the map. On one side the path leads to a small cave housing a Sniper Rifle (Blue side), on the other side this path leads to another small cave which houses a Magnum (Red side). Upon exiting the cave with the Magnum a small ledge is visible which gives you access to the Rocket Launcher. The bases on this map consist of multiple entrance points. Each has an underground entrance out front and on the left sides that connect underground and lead up to the hallway that is accessed by the main front entrance.

All hallways eventually lead to the main room which, depending on the game; will house either the bomb planting site or the flag. Both bases have two way teleporters at their rear. At both sides of the bases the roof can be accessed by either the rocks that are sitting there or by the stonewalls. Two glass windows are used to gain access to the base from the roof. One window is above a hallway near the lower entrance and the other is above the main room.

The Overshield has also been moved from near the teleporter to the middle of the map, in the river.

Tactics

 * 1) The pathways up the hills next to the bases each lead up to a wonderful sniping position. Both also contain a sniper rifle in default games, and it's very difficult to be killed except for assassinations and other snipers. If your team can hold the sniper rifle spawns, and are halfway decent snipers, you will almost certainly get a victory.
 * 2) The space in between bases and the teleporters are definitely the hot spots for battles. Keep this in mind, and navigate around/above/into, depending on your situation.
 * 3) You can super bounce into the tree near the red base sniper spawn, but it's rarely worth it.
 * 4) You can get onto the roof to either hold a tactical defensive position or evade an enemy.
 * 5) There are boulders on the sniping points and on the big arch. Try to melee them off onto an unsuspecting enemy and see their reaction!
 * 6) The tight corridors of the bases make it almost impossible to sneak in there and get the flag and get out in one piece. The solution? Crouch walk! Although it may be slow but you'll be invisible on the motion tracker so enemies are quite likely to run right into you and you'll be ready!
 * 7) If you and/or your team can grab the rocket launcher you'll be unstoppable as long as you regularly grab more ammo. In CTF have one person grab the flag while the rocket man covers him. Or have the rocket man run a distraction while some one grabs the flag. But you have to watch out for snipers or you will have some problems.
 * 8) The Noob combo is very useful in the map - many weapons can be dual wielded to good effect. If you are decent with the Battle Rifle, you and your team can easily win the match.
 * 9) It's possible to hang onto the windows of red base (the ones at the sides closest to teleporter). On the side with the plasma rifle, jump onto the rock and jump while the whole time using crouch and steer into the window and you should stay on it. This allows a person to surprise anyone in the room allowing for a good field of fire and little protection for the people inside. Though it is possible to hang onto the adjacent window, it requires a grenade jump or second person and would be too awkward to get up there.

Easter Eggs

 * If you push the rocks down on the sniper tower, there will be a message engraved on the wall that reads "Why Am I Here?" which is a reference to the Red vs Blue machinima.

Miscellaneous

 * The model of Beaver Creek is the exact same one that was used for Battle Creek with the only difference being the team base colors and the removal of the ladders that led to the sniper spawn points.
 * In Halo 3, there is a map called Ber Ber Creek which takes place on Sandbox and is basically Beaver Creek with Sandbox objects. It is playable in Action Sack.
 * This map is reintroduced as a Forge variant for Battle Canyon in Halo: Combat Evolved Anniversary
