Valve already announced that the upcoming shooter BioShock 2 will be available through its digital distribution service, Steam. Those who pre-order the game will save 10% off the regular price and receive a free copy of Bioshock to boot. The game will feature DRM security. If you buy the game via Steam, you'll have to be logged in to Valve's service, wait for BioShock 2 to unlock, wait for SecuRom activation (and install limits too, probably), then log in to Games For Windows Live once the game has loaded, and then use it exclusively for multiplayer (aaaaarggh!).
