yessss 24-36 players on 1 map. cause games arent laggy enough you feel doubling or tripling the amount of players would be a great idea? sorry but this is just a haneous idea. town and farm would be overrun with riot sheilds and shotguns. everyone but 2 or 3 people would be set up sniping somewhere on green run.
not to mention the amount of bs they would have to do to tie all the MP maps into the zombies storyline. i think its stretched far enough with what we have now. you and your friends have not thought this through very well and its a total waste of thinking.
