Gears of War is turning into a board game, courtesy of Fantasy Flights. Four players get to team up against the Locust, using cute plastic figurines (or not that cute, but very small at least) and different types of cards. The missions you get will be randomized so you shouldn't, in theory, be able to get the same mission twice.
Check out the full info on Fantasy Flights' website. Hopefully Gears of War-fans will be able to pick this up at a well-stocked board game store in the near future.
