GameSpy has put up a preview of Stubbs The Zombie. They liked how the ability to create more zombies that you can make follow you made otherwise straightforward killing far more interesting:

These simple dynamics turn the repetitive combat into a shambling, decomposing chess game, since your inability to singly defeat the large crowds couple with the NPC zombies' natural ineptitude necessitates strategic manipulation of each situation to come out of it in your mostly-intact state. Often I would find myself using zombies as walking shields, hanging back until I could slip in behind the enemies and chomp them, or sending a diversionary swarm towards a machine-gun nest while I hid and send my arm off to possess a shotgun-toting redneck who could take care of the situation.

(The more I hear, the more I'm looking forward to this game--Ed.)
