Square Enix has released the first actual in-game trailer for Deus Ex Human Revolution. The gamescom trailer, which also consists clips from the demo shown at E3, shows main protagonist Adam Jensen on the hunt for someone called Tung in a nightclub in Shanghai, Hive. The action starts picking up really fast in the latter half of the trailer as Jensen goes on a rampage.
Deus Ex: Human Revolution, a prequel to the original Deus Ex which takes place 25 years before the events of JC Denton, releases early next year on PS3, 360 and PC.
