Get outside of multiplay level
From Glitches
From the game Halo 2 for the Microsoft XBOX.
On the map that has the buildings and the road jump in the middle of the level, set it to slayer and the vechicle as Banshees and Warhogs. Set the weapons to the 'Energy Sword' and the sub-weapon as a 'Rocket Launcher'. Make sure you have at least two people before you start this as well. Now, get into the Banshee and fly into the area that is right above the Warthogs, and get out. Throw the Banshee off of the edge and have your friend get up there as well. Go into the corner that has the low ledge, and have your friend jump on top of you. Use the Ultra Jump glitch to get up there (it's small, don't worry). Now use the glitch Sword snipe to get both people up there. Congrats, you're on top of the level. Now if you're really good at the Ultra Jump, you can get on top of the extremely large buildings.
