Eidos has declined to comment on rumours that Tomb Raider Anniversary is heading to Xbox 360.
Speculation erupted after a listing for the game was found on the Entertainment Software Ratings Board website. It suggests that four different missions, or maps, will be released on Microsoft's console - probably through Live Marketplace.
Both release date and price are yet to be set.
Tomb Raider Anniversary is a revamp of the first game in the iconic action series. It's built on the Tomnb Raider Legend engine - the same one featured in the Xbox 360 game, which suggests it wouldn't be too difficult for developer Crystal Dynamics to replicate the adventure.
