We've built a 2D platformer based on inFAMOUS - the PS3 game where you have electrical superpowers. You will need a decent spec machine to play this as we built it around a physics engine rather than just a bog standard tile engine. You'll see why we did this when you use the Shockwave Blast weapon to hurl boxes and cars about the screen.
And we did build this for Playstation who allowed us to upload it here. It's also on the official inFAMOUS site but we didn't steal it... we built it :)
