Treyarch has made cool-looking stuff in the Call of Duty video games, including the introduction of the series' fan-favorite Zombie modes. You wouldn't know it, though, for how boring their offices looked. But, thanks to art collective IAm8Bit, visitors can now tell that these folks really know the undead.

The video above gives a look at how one hallway in Treyarch's Santa Monica offices got turned into a zombie attack zone. The game developers funneled their ideas of what the finished space would look like and IAm8Bit provided the elbow grease—and fake blood—to make the transformation happen. All it needs now are guns.
