Get Out of Coliseum

Ok, I know that there are tons of you out there who have absolutely no idea how to beat general corrosive when your in the arena if all they give you is a wrench. here's what to do with it. run under one of those metal shelter things. when you get there, use the wrench to take yourself apart. when general corrosive rips it off, he'll think your dead. they will then show a cinematic of you being thrown into the scrap yard, and you'll be free. all your weapons will be there, and one of those car things. pick up your weapons and drive to the launch pad.

Fun at Big E's House

While at Big E's House, take control of the Trooper with the control tether. Then, walk to an area that is outside. Take the elevators until you are at the top. Then you should see a waterfall. You can use your jetpacks to get on top of it. It takes a lot of practice, but you can eventually do it.

Mogul, Schmogul

When you play the level "Mogul Schmogul", reload at the beginning. This gives you five more shots. Also, press the secondary fire button to swing Mogul's club. This kills the "oil thirsty monsters" in one hit, and everything else but a vehicle or turret, too.

Secret Ally Robots

When playing multiplayer, if you destroy enough enemies without getting destroyed yourself you get a message saying "Brawling Bot Supreme". It would be the second message you would receive not the first. If that message shows up you will receive 3 robots that will help you defeat the enemy. The message will show up after killing 6 enemy bots without getting killed. This code only works if you play another person not the CPU.

Fun way to play with mils

Start a multiplayer game with just recruiter grenades as your secondary weapon. It doesn't matter whether you are playing alone. Go to a level with multiple mils, have them be off when not recruited. Recruit two or more, and hide behind one as you pop off a couple of shot at the other one. The one you fired on will fire at you, and thus hit the mil you are hiding behind. They will fight each other and not hit you, while u just stand there laughing. This is best done on the level Tanks a Lot, with 3 mil Titans.
