Alien: Isolation Complete Walkthrough and Game Guide

Alien: Isolation Complete Walkthrough and Game Guide

Alien: Isolation is a survival horror game with a heavy dose of stealth, and we should also mention that it is absolutely nothing like Aliens: Colonial Marines, a game that was received rather negatively, to say the least.

The good news is, while Gearbox Software was responsible for Colonial Marines, The Creative Assembly are the ones who have expertly crafted Isolation. That’s not to say that Gearbox Software isn’t a great studio, but for anyone who might be inclined to carry some bad blood from one to the other, we’d advise you to give Alien: Isolation its fair kick at the can.

The game takes place 15 years after the events of Alien and 42 years before those of Aliens, the first two films in the franchise. Players will step into the shoes of Amanda Ripley, daughter of Ellen Ripley and series protagonist. Amanda is given the opportunity to investigate the disappearance of her mother, joining Samuels and Taylor on a trip to the Sevastopol, a space station that holds the flight recorder from her mother’s ship, the Nostromo.

While the plot certainly does get much, much thicker, we have no intention of spoiling it for you, opting instead to provide you with this free walkthrough. Let us guide you through some of the more difficult situations you’ll encounter on Sevastopol, leaving the story-telling to the game itself.
