Sniping location

Fly up to the center machine in a Banshee. Park beside the ledge with the moving metal "shield". Go inside the room. The metal shield will block, and you have a very good view of half the level and a shield which repeatedly falls over, blocking you from enemies. If someone finds you, wait until the shield drops then run around the ledge to the other side of the level and start sniping from there.

At any base, get a Banshee. When in the banshee, fly to the center building structure. Fly all the way up to the top of the structure where the metal object rises and falls. When you are there, go to the level walls and try to land the Banshee on one of the ledges. Every time the metal object rises and falls, the Banshee will move. After awhile it might fall, but that is acceptable. You can also fall and not get hurt. If done correctly, you will have a very good sniping location, while very high and almost invisible by the shadows.

Locate the big "building" (the thing in the middle).You will need a Banshee and a lot of ammunition. Drive the Banshee to the bars on the building. Land on the bars, but make sure you have a place to hide. Once there, you can kill your friends.

Get the Banshee and a sniper rifle. Fly up to slanting beam-things in the middle of the stage. Go to the higher set of beams and land the Banshee carefully or you will fall off. When you land correctly, the Banshee will slide down and eventually fall. There is another beam; you can snipe from either side and are almost invisible to players without sniper rifles or Banshees.

Wormholes

 Xbox  On a game-type with a bomb, have control of the bomb. Then, have someone plant the bomb while you wait where it respawns. Once they have scored and you have the bomb, go to your base and get on the roof. Once there, go to the left side and jump on the ledge. There should be an outcrop of rock where you can get onto. Once on it, turn so that you are looking in the corner. Aim straight down and press R. This should open up a "wormhole" in which the bomb is under the ground. Note: If the person that opened the wormhole dies, you must have someone standing where they opened it or the bomb will come out.

Saved by boost

While in a Ghost, Covenant Warthog, or Wraith, if you get pushed into the middle slowly and you are falling next to the wall at the right angle, you can turn around and activate boosters and push full forward. You CAN get back on the stage (and hopefully have a rocket launcher to blast your opponent).

Easy capture the flag

This trick requires at least three people (four or five recommended). Have three people get into the Warthog. If you can spare a fourth person, have him get in the Ghost, and a fifth person get the sniper and go to a good point to cover the top of the enemies base. Note: The fourth and fifth persons are here to help the three in the Warthog and are optional. Have the people in the Warthog and Ghost drive to the side of the enemy's base (by the side with the box where you can jump up to the top of the base, and the window looking into the lower floor). If there is a sniper covering them, have him clear or scare off everyone from the top of their base. The Ghost should stay outside and cover the Warthog. Have only the person in the side seat of the Warthog get out and jump up to the top of their base. Have him then jump down though the hole in the base and get the flag, making sure to get it next to the window. The person in the turret of the Warthog should now jump out, grab the flag through the window, then jump into the side seat of the Warthog. Then, drive back to their base.

Falling stalactites

To make the stalactites fall, shoot them with a few battle rifle bursts or a few sniper bullet shots. Rockets will shatter the stalactite. Once fallen, the stalactite provides a temporary blockade for entrances to buildings, as well as a very powerful weapon if you are skilled enough to have it land on someone.
