Mass Effect 2 Previews

BioWare's Mass Effect sequel is the subject of a couple more previews, courtesy of the demo being shown at GamesCom.

NowGamer:
The main difference shown in this demo is the combat. As we fight our way through a number of security robots, it's clear that the cover system and enemy AI has been greatly improved. The action feels natural and ordering those with you to attack or hold back feels far more instincive than in the previous game.

And YourEMGN:
Mass Effect 2 takes place two years after the conclusion of Mass Effect. With the Reaper invasion stopped and Saren and the geth defeated, Commander Shepard learns that entire human colonies are mysteriously vanishing. Teaming up with the human supremacist organization Cerberus in his investigations, Shepard will also journey across the galaxy to recruit "up to a dozen of the galaxy's most dangerous operatives" to face this new threat. Locations include the asari colony world of Illium, and Omega, a space mining station in the Terminus Systems which harbors the worst of galactic society.
