Mmm sounds just like CS:S zombie mod... but thats a good thing!!! I am aware that i have posted this CS:S zombie mod stuff in a few other threads, but for the people that don't know according to gametracker the top 3 servers are all zombie mod. Most of the stuff zangetsu said about this new "zombie mod" sounds just like CS:S zombie mod. I attached a screen shot of the top 3 servers for CS:S. Also checked, and made sure there's no bots. When i took a look at the second ranked server i realized that i used to play on that server like 3 years ago. ahhhh good memories. I also attached an CS:S zombie mod vid.
*THE SOLE POINT OF ATTACHING THE VID IS TO SHOW SOME OF ZANGETSU'S IDEAS*
http://www.youtube.com/watch?v=uOajNIBrNXc# If you pause at 0:22 of the vid you can see its like 4v13, but in CS:S in start its only one zombie that spawns which isnt gonna happen, and when you see the knife kills by the zombie (top right of vid), the humans then transfer to the zombie team which led to it being 4v13 not 1v13. Eventually when everyone gets to the zombie team usually it will just end the round in like "zombie team wins!", or else then if all the zombies are killed it would be "human team wins!" and then it will just go back to another round of zombies/humans, and start again
Other then that great idea!
