Microsoft's Games for Windows Marketplace is having a buy one, get one free sale on Epic Games shooters starring guys with really big arms. Specifically, the digital storefront is giving anyone who buys next week's foul-mouthed FPS Bulletstorm a free copy of the original Gears of War.

The deal will be valid from February 22 -- Bulletstorm's on-sale date -- through March 8. People Can Fly's game will carry a sticker price of $59.99, while Gears normally goes for $19.99.
