Sony is giving away four – yes, four – PlayStation Minis to gamers who participate in a spot of viral marketing this holiday. In order to unwrap the goodies, all you need to do is visit the manufacturer’s Facebook page and follow the simple instructions. You'll need to bombard your friends with plenty of promotional material in the process, but that’s a small price to pay for free copies of Velocity, BreakQuest: Extra Evolution, Canabalt, and Wizorb.

Sadly, the promotion is only open to European users at the moment. Those of you in North America will have to make do with a lump of coal.
