One of the more cerebral things to do in Sega's Alien: Isolation involves reading all of the messages/emails stored on Seegson computer terminals, piecing together the tragic events that befell Sevastopol Station before Amanda Ripley arrived. How did an Alien get on board, and what happened to the Nostromo flight recorder from the doomed ship? For Alien fans, the backstory greatly enhances the plot, and it's fun uncovering new shreds of info.

On that note, Sega and Creative Assembly will provide additional morsels with the upcoming Corporate Lockdown DLC, which debuts October 28 across all platforms for $7.99/€6.99/£5.59.  In it, players will attempt to outwit the Alien across three brand-new Survival Mode maps called Severance, Scorched Earth and Loose Ends. Instead of playing as Ripley, they'll control executive Ransome, who attempts to hitch a ride on Amanda's ship, the Torrens, with precious Nostromo data.

The new maps come with unique bonus objectives, and the Alien: Isolation Gauntlet Mode tasks gamers will finishing these levels back-to-back-to-back without dying once, which seems impossible given the Alien's intelligence, ferocious nature and high probability of player error.

Quoting Ash from the original Alien: I can't lie to you about your chances, but... you have my sympathies.

Sega hopes to release all Alien: Isolation DLC by March 2015, with remaining add-on packs Trauma, Safe Haven, Lost Contact and The Trigger on the way. On that note, you may want to consider buying the Alien: Isolation Season Pass to receive a 25 percent discount on all downloadable content.
