Collateral follows a soldier who is given the task of infiltrating an enemy base to find proof that the bad guys have nuclear weapons. Created for Ludum Dare 18, the twist is that you can't die - instead, getting hit by enemy fire will launch you higher, which is especially useful for later in the game.
The baddies will fire back at you when you're in range, but if you manage to dodge out of the way, any stray bullets will bounce off walls and bounce back, potentially killing them. The game tells you to 'kill them all' at the start, but it's actually more interesting to see if you can complete the game without a single fatality.
Go and play before you watch the above video, as it shows a complete walkthrough.
