This is a prequel to Alien Isolation, before Amanda Ripley and her team arrived in Sevastopol.
The settlers at Sevastopol Station go about their day, knowing that it is only a matter of time before Sevastopol is dismantled. The Seegson company, its current owner, no longer finds profit at the station, has withdrawn funds for mineral extraction projects.
In the midst of the station's spiral of decline, a dangerous alien organism has been brought aboard the Sevastopol. An agile, strong, cunning predator capable of learning from humans as it observes their behaviors.
Needless to say, this is not a story with a happy ending. There is no way to prevent what is going to happen to Sevastopol and its inhabitants. This is their story.
