Deus Ex: Human Revolution to Last 20 Hours

Speaking to NowGamer, producer David Anfossi, reveals the critical path of Deux Es: Human Revolution will take 20 hours to complete, which is longer than most modern-day single-player games.

"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."
