Of course, developers program their titles to carry out specific functions and act in certain ways – after a brief time in most games, enemies, worlds and even the entire experience itself can be easily telegraphed.

Enter Left 4 Dead – Valve's much touted, zombie frag-fest. Each experience of Left 4 Dead is different, from the location of enemies and weapons right down to the mood music and effect, and it's all thanks to a sadistic bastard named "the director." Though not a character per-se, the director system plays as much an integral part in the Left 4 Dead experience as the four survivors or zombies themselves."
