Worldcrafter: Here be Zombies

Any game worth its salt must have the current "enemy du jour" in it, which these days seems to be Zombies.

Here you can see one of the little blighters trying to creep up on our hero. What can he do to save himself? At the moment he can either run, or mine some rocks and throw them at it. But more may be waiting round the corner. They normally only come out at night, but thanks to my new and patented "debug mode", I can conjur them up whenever I want. What's that you say? "Prior art"???
