Mass Effect 2 adds Kasumi pack April 6

Mass Effect 2's Firewalker add-on pack stands poised to inject a healthy dose of new content into BioWare's critically acclaimed sci-fi role-playing game for the Xbox 360 and PC tomorrow, March 23. Following the release of Firewalker, ME2 fans won't have to wait long for the game's next infusion of content.

BioWare has announced that the Kasumi - Stolen Memory add-on will arrive for the PC and Xbox 360 on April 6. Unlike Firewalker, which comes with no charge to users who downloaded the Cerberus Network ($15 or free with purchase of a new copy), the Kasumi pack will cost gamer $7 (560 Microsoft points).

As detailed in GameSpot's first look at the add-on pack from this year's Game Developers Conference, the pack's primary draw is the addition of the titular new character, Kasumi Goto. Described as a master thief, Kasumi comes with her own loyalty mission in which players aid her in stealthily retrieving information from the criminal mastermind Donovan Hock.

The Kasumi - Stolen Memory pack also includes a new research upgrade and introduces the flashbang grenade, which temporarily blinds enemies. The add-on pack also includes new achievements. For more information, check out GameSpot's previous coverage of Mass Effect 2.
