First to the easy stuff, most of all people know that crouching in mid air can gain you up to about a foot of hang time (amount of time in air) and height. Well, we're lucky to have and know this because you will need it.

On Headlong, put a wraith on the map and give every one an overshield. It is best if you modify an existing game type and have everyone start with overshields. Then go to the area where you can get a Banshee, look at the building and turn right, go staight, then to the middle section of the lower wall. Have one player go with their back straight up against the wall, and have another player in the wraith go as far back against the wall across from the other person.

me and my cousin have found a new glitch. if you throw a grenade the right distance away from a machien gun turret, then the grenade will explode and destroy the turret but the rod in witch the turret was siting on will still be there. Go up to the rod and an imadinary useable turret will be there and you can still use it. (note that the if the grenade is to close then it won't work, also if the frenade is to far away then it won't destroy the turret). You have to get it just right, or it won't work.

In multiplayer a variation of the Sword Flying technique exists, but it requires split-second timing and performing it consistently is difficult.

With the sword as your reserve weapon, take another weapon and find a target; a scoped weapon with a reticle that turns red when locked on a target in range, such as the rocket launcher, is preferable.

Then, switch to the sword and pull the trigger. If the switch and pull are timed correctly, you'll perform a lunge attack regardless of the distance between you and the target.
