And when we say 'suicide mission' we mean it would be suicide not to take this mission. That slight note of terror you're hearing in GLaDOS's voice is probably just an audio calibration error. Did we say 'dangerous'? We meant routine. You and your co-op science partner are once again awoken and assembled for a dangerous new mission. An all-new co-op adventure starring Atlas, P-Body and GLaDOS, the free DLC 'Peer Review' takes place an unknown period of time after the events of Portal 2.
