25 minutes worth of gameplay footage of Eidos’ upcoming RPG/shooter sequel, Deus Ex: Human Revolution, have cropped up on Youtube, supposedly leaked from a Russian press site. The footage seems to have been captured from a press event, and is likely taken from the game in pre-alpha state sometime in 2010.
Therefore, we can assume that the game will have been touched up a bit since this footage. The videos show off some neat gameplay mixed in with cinematic sequences. A basic dialogue system is shown, as is a cover system.
Deus Ex: Human Revolution is due out sometime this year, and will be released on PC, PS3 and Xbox 360.
