Fighting zombies is very satisfying in Dead Island, mostly because of the ability to chop off or crush limbs, and the need to, in many cases, also stomp the head of a downed zombie to really kill it. One thing that is interesting is how the game actually uses its animation system to procedurally adjust a character's head-stomp animation, rather than magically moving the stomper's body to the proper location to do a canned animation.The system still needs work, though, as there are some pretty funny bugs with how it looks from another player's perspective.
