"We've gone down the road of implementing Steam DRM where we've committed to the US being an exclusive and we're going to make a decision as to whether or not we'll use different distribution channels," brand manager Karl Stewart told CVG.

Stewart explained "the biggest fear we have is that people are going to be inquisitive and are going to [illegally] download it" because "Tomb Raider has traditionally been a single player game" and the spin-off packs online co-op. "We have the risk of people saying, 'I never really wanted to play the online mode, I just want to play as a single player.'"

Downloadable PlayStation 3 and Xbox 360 editions of Lara Croft and the Guardian of Light are also in the works, with all three versions due out sometime this summer.
