Today, Sega announced five DLC packs for Alien: Isolation, the first of which will be available in time for Halloween should you wish to scare yourself even more witless. ‘Corporate Lockdown’ will be available on October 28th and priced at US$8. It includes three new maps for the Survivor Mode and a new challenge, called Gauntlet Mode, whereby players must complete all three new maps consecutively, without dying once. Rounding out the package will be a new playable character called Ransome, a Seegson executive. There are four more packs to come, exact release dates are yet to be announced but Sega says they will all arrive by March 2015 and are included in the Alien: Isolation DLC pass, available for US$30.
