Mass Effect 2: Overlord

In Overlord, players will take Commander Shepard and his crew to investigate a Cerberus research base that has mysteriously gone silent. They arrive to find that Geth troopers have overrun the base. The sole survivor paints a dire picture: an experiment to fuse a human volunteer with a virtual intelligence has created a dangerous hybrid VI Overlord. The rampaging VI Overlord has already attacked three other Cerberus bases, taking control of any technology it finds—and unleashing hostile Geth across the planet in the process. Unless Shepard can infiltrate the VI’s fortress and shut it down, this homicidal intelligence will beam itself off the planet and wreak havoc on other systems throughout the galaxy.
