Devil of a genius

I played it and 1,2,3 with my 3 friends and think this series so fun!
Though we use admin mod otherwise we never get through it :P

So great!

This map is so great! I think it can be one of my favorite maps! The zombies are so many but not feel too hard. There also something I think could improve: In map 2 , it is easy to get lost underground, the Guide Sign could be more.  In first 3 maps the ammo is little. Through I'm using double ammo mod, I also think ammo is not enough. Maybe I just didn't found the ammunition emmmm...
(ex: Using 3 turret to defend flood hordes is so coooooooooool!)

Fantstic Map!

Great map! I love it! By the way, I wanna konw that the subtitle is valve's deleted part? Or the subtitle is specially made for this map?
