Length is always a concern when it comes to single-player adventures.

And if you're wondering how long the new Alien: Isolation will be, we've got some good news:

According to lead game designer Gary Napper speaking during a recent Angry Joe interview , Creative Assembly's new game will take about 15 hours to complete.

This is indeed a linear adventure, but Napper promises that players will have plenty of opportunity to explore. He describes it as "a bit like a 'Metroidvania' game," in that you can return to previously explored areas and open up new areas. I've always liked that setup because it forces you to keep a map of your travels in your mind, and I always loved it when I'd say, "Oh, I can use this to get over there!"

Of course, there's no guarantee you'll spend 15 hours with the game. As Napper explained:

"The difficult thing is nailing a time because people can play for absolutely ages without even seeing the alien because they're being really careful and really stealthy. They've done nothing to call him down or there have been no explosions that he has come to investigate. Those people can get through it fairly quickly."

Alien: Isolation is set to hit the PlayStation 4, Xbox One, PlayStation 3, Xbox 360 and PC on October 7. And no, it's not a shooter; it's actually more of a survival/horror game, which sounds perfect when one considers the original "Alien" film.
