Alien: Isolation - Corporate Lockdown
Choose from playable characters B. Ransome, Ellen Ripley, Axel Fielding or Hughes and attempt to escape from the Sevastopol Station in this single player expansion. This DLC includes three maps; Severance, Scorched Earth and Loose Ends. Corporate Lockdown also includes Gauntlet Mode, where players are prompted to complete all three missions back-to-back without dying.

Alien: Isolation – Trauma
Set during the events of Corporate Lockdown, Trauma sees players take control of chief medical officer K. Lingard, collecting medical supplies for her camp as well as destroying any of her existing research on the Xenomorph alien to prevent it falling into the wrong hands. The DLC features the Reoperation, Crawl Space and Overrun maps – and players can also opt to play as Amanda Ripley, Dallas, Ellen Ripley or Ricardo – instead of Lingard.

Alien: Isolation - Safe Haven
In Safe Haven, players control Hughes in what was the first DLC which introduced the Salvage Mode. After finding the only safe room in the Sevastopol Station, you’ll be tasked with venturing out of your comfort zone in order to gain supplies – dodging certain encounters with not-so-friendly Xenomorphs.

Alien: Isolation - Lost Contact
Guide Axel Fielding on a mission through challenging tasks during his fight to survive. Play through the second all-new Salvage Mode map, featuring Lorenz Private Wards and the Emergency Power Plant.

Alien: Isolation - The Trigger
PLay as deputy Ricardo, member of the Colonial Marshal Bureau, as he is sent by marshal Waits on a dangerous quest to place explosives in the Sevastopol Station to, hopefully, kill the Xenomorph Drone slaughtering the station's remaining population. Journey through the Damage Control, The Package and Blast Seat maps as Ricardo, K. Lingard, Amanda Ripley, Dallas or Dennis Parker.
