Mass Effect 2: Overlord

Backwards compatible DLC.

Overlord is a commercial, almost completely combat oriented downloadable content (DLC) pack for Mass Effect 2. An AI named "VI overlord" has gone rogue, attacks Cerberus bases and unleashes Geth. Of course Shepard has to shut it down... The quest series leads the player to five new areas which partly include the usage of the Hammerhead which was introduced in the Firewalker Pack DLC.
