To be honest, I thought this was new! But indie developer Mobeen Fikree, let me know this was kind of always the case, as announced on the PlayStation Blog comment page. Mobeen Fikree even tweeted some footage of the game.
We Are Doomed is currently out for PS4, Xbox One, and PC, but the Vita version is planned for an early 2016 release. Let us know in the comments if you want to play a portable We Are Doomed!
