Super Smash Bros. Brawl/Battleship Halberd Interior

You start out as Snake, so you can pretty much beat all of the R.O.B.s without too much trouble. Then you hide in your cardboard box again as Lucario and Meta Knight walk by. Lucario senses you, so you join up with them to defeat a lot of Primids. You eventually free Zelda and Peach, then you leave.
