Here's a new trailer for State of Decay, a ridiculously ambitious RTS/shooter/zombie survival game that will be out this June for XBLA.
Why don't zombies ever eat each other? No really.
They want brains, right? And to kill one you have to cap it in the head and destroy its brain, so obviously the zombie's brain works even if it only offers lower level functions. Yet they only ever chase after the living humans and only if they see the humans not acting like zombies themselves. I think they've been tricked into believing that living human brains are better for them somehow. They should eat each other. How many times has a hoard of zombies chased after a couple living stragglers when they could have far more easily turned on each other and had a filling meal. Idiots.
