Alien Isolation's original film cast pre-order bonus is no longer a pre-order
Were you bummed that you coudn't play with Ellen Ripley and company in Alien Isolation without pre-ordering? SEGA announced some fantastic news that will lift your spirits: you don't need to pre-order the game for the add-on!
Here's a full statement from SEGA via Kotaku:
So there you go. You can recreate scenes from the original Alien movie without blindly putting money down towards a game that may or may not be worth the money.
Sadly, the "more details" probably mean that it'll be offered as paid Day One DLC.
