Not really a contribution as its all based on George's Purrfect AI.

Here is his original level working with multiple entities (10 in this level). All the code is mainly from ai2, ai4 and pai.wdl (from goodies section)

The enemies do skip through walls sometimes to nodes but I believe this is due to too much close proximity of the nodes to the walls....but I could be wrong :P

Anyway have fun if you can use this and for goodness sakes read the original AUMs (27-31,64)

up/down arrows for forward/reverse
left/right arrows to rotate
