You'll need to reschedule your online date with Lara Croft or her immortal Aztec tribesman pal Totec. The PC and PSN versions of Lara Croft and the Guardian of Light will not launch with online co-op as was assumed. It will instead be added to the games "at a later date" beyond their respective September 28 releases across the aforementioned platforms.
Online co-op was an expected part of these two versions of the game, perhaps as a result of the their proximity to the planned release date of a patch that will add online co-op to the Xbox Live Arcade version of the game (which itself bafflingly launched in August without the support). Local co-op, though, is still go for the PC and PSN versions, and for what its worth, the functionality works well. But, yeah, the whole having-to-sit-with-a-person-in-the-same-room thing is a drag--especially, when you want to be Totec.
But in other news, there also appears to be a bit of wavering on the arrival date of the XBLA version's co-op patch. A Crystal Dynamics representative has told Joystiq that the support update will be coming "in the very near future," instead of pegging its previously announced release date. Odd.
The failed full launch of the XBLA version of the game is presumably the core reason why Crystal Dynamics will be offering the game's first bit of DLC for free for the first 30 days of its existence on Xbox Live. This news makes us wonder if that offer won't be extended to the PS3 and PC, as well.
