Square Enix Montreal has confirmed that upcoming cyberpunk sequel Deus Ex Human Revolution will last around 20 hours

"The duration of the game is roughly 20 hours - only on the critical path," Producer David Anfossi confirmed to NowGamer. "In a first-person type of game you don't really see that very often."

Asked whether the game would spawn a new generation of deep, cyberpunk action RPGs, Anfossi added: " We're trying to have this cinematic feeling to it, and we're trying to work on what the charscters are going through, their emotions and what motivates them to move forward. I think if it's done well, it's going to inspire other people."
