something i stumbled upon while playing the PS3 version of Strongbad: Dangeresque 3.
you can do this at any point in the game, including right at the beginning.
if you open your map, press R1 then X twice, you will jump right to the end of the game to the space shuttle fight scene (or whatever it was). of course, this is game breaking since your inventory is the same as it was when you did this, so you won't have the right items to get out of that scene.
just thought i'll let you know in case you didn't already :D tried searching for it but found nothing.
