Simply put, this mod fills out the game’s spartan bestiary by adding more creatures, some of them relatively exotic, including: jellyfish, stingray, mantaray, ostriches, ogres, wraiths, polar bears and werewolves (yes, werewolves). Several of the creatures are interactive, like “kitties,” which can be tamed and fed, or “bunnies,” which can be dropped like radar countermeasures to throw off attacking mobs.
