Well, there's a funny story about why undead spawn in the ocean. I soon as I can get the new resource system working for undead I'll post an update. I'll also correct the undead spawning to never spawn in the ocean. I am trying to get the time limit back down to 15 minutes because I feel that 20 minute rounds are too long. The new update will speed up the undead's progression through their tech tree. Humans will be getting a few new buildings and other tech adjustments.
