The DLC follows events of two days spent onboard a ship. The player is isolated from the support networks found in the core Human Revolution game, and must face events independent of comm advice.
While travelling, the player discovers the vessel is a floating prison of some kind, and that experiments are being carried out on the inmates. Environments include plenty of cells and a sentry tower.
Itís not clear whether the DLC is an event tied to Human Revolutionís plot, or part of the broader Deus Ex storyline Ė perhaps an episode from original protagonist JC Dentonís adventures, which would explain Eidos Montrealís promotional build up.
