Monsters vs. Aliens

This isn't as hard as it may seem. Don't rush things too much, especially on B.O.B.'s scenes where he can fall easily. The game auto saves, so if you do fail you will need to quit the game. If you fail and then quit from the pause screen, the game will save also, so you need to use the PS button to quit the game completely.

And remember, failing is losing all your health or falling off a level and you will see the -2000 points pop up in red as you respawn.

If you didn't do this on your first playthrough you will need to start a new save game and replay through the game as going back and replaying the scenes won't work. So it's best to focus on this the first time through.
