"I'm blown away by how far we've come in such a short amount of time. Our task now as we move headlong into the production phase is to take this fun little gem and turn it into something we're proud to show the world," Strain wrote.
The gem he's referring to is currently known only by its Class3 codename. We do know that it's about zombies and that it's only for consoles. Aside from that, the title is shrouded in a fair bit of mystery. Strain's post also features a time-lapse video that shows off the game's CryEngine 3-powered time-of-day effects, and you can check that out after the cut.
