The incredibly hardcore survival horror game has now received both critical acclaim and partial commercial success. The Creative Assembly has announced today through their Twitter account that Alien: Isolation has surpassed one million copies sold.

As much as this does have a strong property behind its name, it's still an impressive feat for a title as it's not something you'd normally see break into the mainstream. Regardless, Alien Isolation has turned out well, hopefully sparking even more support for the series moving forward.

It’s a great day. A huge thank you to all who helped us reach this fantastic number! http://t.co/MNVC2qgjwR pic.twitter.com/HSlUwv1sPM
