At E3 Microsoft and Bethesda unveiled Redfall, a co-op Left-4-Dead-style vampire game featuring developer Arkane Studios’ trademark open-ended gameplay. Redfall certainly looks promising, but the game was kind of announced out of nowhere and won’t launch until 2022, so how long has it been in development? What kind of resources is Arkane putting into it?

Well, apparently, Redfall has already been in the works for quite some time. According to the LinkedIn page of environment artist Francisco Cruz III, he began initial work on the game only a few months after Prey shipped (thanks to Twitter user and frequent Microsoft dirt-digger Timur222 for surfacing the info).
