On March 19th, Tomb Raider on the Xbox 360 will be receiving a timed exclusive multiplayer downloadable content, similar to the other games where Microsoft snagged a DLC exclusivity.
The new DLCs that will be available on March 19th will add three new multiplayer arenas: Scavenger Caverns, Cliff Shantytown and the Burning Village. When it hits the Xbox Live Marketplace in a few weeks, the DLC will carry the price tag of $5.
