Following last week's dev diary featuring Undead Labs' art director Doug Williams and his talk on the "heart of horror," the most recent dev diary from the studio shifts in a more technical direction. In particular, executive producer Jeff Strain focuses on the game's engine. Even more particularly, he announces that the tentatively named Class3 will be running on the powerful CryENGINE 3.

Of course, the devs over at Undead Labs are quite familiar with the traditions of the internet and anticipate shouts of "pics or it didn't happen" with a lovely screenshot from an early version of the game. But wait, there's more! Call now and you'll receive not just a single screenshot, but an entire video! Just click past the break and check out an early version of Undead Labs' Class3 in action, then skip on over to the dev blog to read the full entry.
