Square/Eidos has just announced that Lara Croft and the Guardian of Light "is to receive a major update on Xbox Live Arcade this Wednesday, October 27, 2010" and it'll also be getting Free but time-limited DLC.
The title update include, "Full online functionality including co-operative play will be activated via a free title update and free downloadable content will be available for a limited time period."
That "free DLC" comes with a little caveat, "The first DLC pack entitled ?All the trappings? will be given away for free for 30 days to XBLA players."
Sad faced PS3 owners, cheer up a bit, "The co-op and DLC update for PlayStation3 and PC players will be coming soon. More details to follow."
