Looks like Crimsonland but with online bits and some zomie-esque critters.

I'm surprised there aren't more zombie based MMO games with zombie themes. Imagine teams of players trying to control areas of abandoned towns, having to find and use limited resources of weapons against a growing number of undead. And then rival player factions could turn on one another to steal each other's bases and weapon caches. Be fantastic. I'm bored with the idea that just about every MMO game needs to have bearded dwarves.
