When your in a map called Crane, Use two Mutators, Rocket Launcher Mode and UT G.O.T.Y. Chaos Mode, the UT G.O.T.Y. Chaos Mode is a mode that you have a field that its defence is thick that can save you in a long time, you can only get this mode when you have the UT G.O.T.Y. Edition. Now Here how it works, 1st use cheats God and Fly after you click, second, Blast your Allies off the building, if there is a message that says [Ally's Name] just dump his on self, do it again with the order Cover Me until they don't die while reachin the down floor that has red and blue lights, then Kill the enemies, if it blast of the building, follow him/her down then kill him/her, but if it says [Enemy's Name] just dump his on self, then find them again, if your out of ammo and picked up an ammo, it won't add ammo to your rocket laucher, just get another rocket laucher and there you go, full ammo.
