Up until now, Alien: Isolation’s Last Survivor DLC was only available to those who preordered the game, but you can now purchase it for $3.99.
The Last Survivor mission puts you in the shoes of Ellen Ripley during the last moments on the Nostromo where you must self-destruct the ship and reach an escape shuttle before the explosion.
