Hvis du er nervøs for at din tur med Alien: Isolation er ovre før du aner det, så kan du ånde lettet op. Om ikke andet ifølge Creative Assemblys Gary Napper, der i et interview med Gamingbolt forklarer at vi kan forvente en spiltid på 12-15 timer.
"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"
