UPDATE: The two sets of DLC announced below will be available to all consumers, whether you pre-order Alien: Isolation or not. The announcement was made on the Alien: Isolation Facebook page:
“It’s genuinely been great to see the reaction to The Crew Expendable and Last Survivor pre-order bonus content we announced yesterday and how excited you all are to re-experience those classic scenes from the original movie with our Alien. It’s been absolutely amazing for us at the Studio.
However, some of you have been asking if the two pieces of content are only available through pre-order or if we’ll be releasing them at a later date as well. So, I can confirm today that we do plan to release both Crew Expendable and Last Survivor at a later date and we’ll have more details for you guys on that shortly.
