In an interview with Gamingbolt, Gary Napper of The Creative Assesmbly discussed how long it should take players to complete Alien: Isolation saying, “The play-time for the game is kind of tricky. Because of the systematic AI and because of the fact that so many different things can happen. You can have some players that will play for a long time and never seen the alien. Other players will have deadly stand-offs and die a few times and maybe some humans might appear or androids. So, we see massively varied game-times from this way. But we are kind of aiming for a 12-15 hour campaign.”
