Crystal Dynamics previously announced plans to launch Lara Croft and the Guardian of Light on XBLA, PSN and PC this summer. Since the XBLA release is now part of Microsoft's Summer of Arcade promotion, however, PSN and PC players are going to have to wait a bit longer for their date with Lara. When asked how long the game's timed exclusivity on Xbox Live would last, Crystal Dynamics' Karl Stewart told Eurogamer, "Well, for exactly four weeks, really. The agreement with Microsoft is, in order to participate in their hugely successful Summer of Arcade promotion there is a window of exclusivity. That window of exclusivity is a set four weeks."
Lara Croft is slated to launch August 18 on Xbox Live Arcade, which would mean that the PSN and PC releases are essentially on hold until September 15. Stewart explained that it's ultimately "up to the first parties and the likes of Steam to agree that's the best date for us." It's worth noting that September 15 is a Wednesday, and North American PSN updates occur on Tuesday now, which could mean Lara Croft's release in the region could get pushed back another week.
