Zombie Master (HL2 Mod)

[McLaren]

If you own Half-Life 2, and have played Zombie Mod in CS:S, you will LOVE Zombie Master.

I've just recently gotten into it, and it's a great way to tide yourself over til' L4D. 1 player controls a GIANT horde of zombies while humans (you) must fight many different types to find the zombie master and destory him while following certain tasks.

Check it out!

Left 4 Dead... I'm actually anticipating that. And I don't even know how the gameplay is!
