Alright, first go to multiplayer mode ( This cheat requires two real people).
Once you choose your guys, set the only weapon as remote mines (all five slots).
Then,once your at feild select,choose the arctic level (the one with the dam).
Now,get one person to flip the jeep over. Now, have the person who didn't flip the jeep over load random places on the bottom with remote mines. Now you flip the jeep over,and have the person who didn't put the remote mines on get in. Now,the person who set the mines blow it up (make sure you're on the same team!)The person on the jeep wil stay in it until they get to this weird glitched place. Now,right when you get to the glitched place,get out of the jeep.
If you followed the instructions, you'll be in Skyland!
