A bundle over at amazon has you getting a free copy of visual novel/puzzler Zero Escape: Virtue's Last Reward with the purchase of a PlayStation Vita.
You'll have to buy one of the bundles listed here to get the game for free. When you add both the system and the game to your cart, the game will be knocked to $0 automatically. If you're interested, you have until 11:59 p.m. (Pacific Time) on December 15, 2012 to buy.
Here's a half hour of the Arkham Origins Mr. Freeze DLC, if you want to watch that
