Buy the Monkey Dogfight party game. Go to the Space Station Zone level. Immediately fly to the bottom of the level. Fly into one of the long cracks in the floor. Once you are in the crack, hold R button. If you just keep flying, you will go through the wall. The other side is completely black. Do not fly too low or you will land in invisible water and drown. If you turn around, you will see the level. If you fly far enough away from the level, the level will no longer be there when you turn around. This is a good place to have major dog fights with your friends. If you want to get back to the level, you will have to look at your mini map or just drown.

Choose the space station level. Fly straight down into one of the "corridors" and go straight. Eventually you will go into the wall and the screen will turn black. You can see the level. This is an easy way to win Survival mode because people cannot hit you and you can hit them. To exit, fly back into the stage.
