The very first map pack for Tomb Raider, Caves and Cliffs, will be hitting the Xbox 360 first on Tuesday, March 19th for 400 MSP ($5). Included are three brand new multiplayer maps, which work in all four of the online game modes, and you can read all about them below:

• Scavenger Caverns: An extensive subterranean network of caves used by the island’s scavengers as an underground prison.
• Cliff Shantytown: This scavenger settlement was built high up on the island cliffs. Its many layers hide some of the deadliest traps on the island.
• The Burning Village: A raging fire has embraced an abandoned Japanese village, the burning buildings offer multiple ways to escape or engage your enemies.

Other platforms will have to wait for the timed exclusivity deal to wear off before receiving the Caves and Cliffs pack.
