That was my idea from almost 2 years ago! -_-
well great minds think alike? XD
Res does have a point about the poisions though if the first person spawns as a poision everyone on the ct team will be ripping that mofo to pieces as for fast zombies they only have like 1000+ hp so co-ordinated players working as a team can normally rip a speed apart. only problem with the speed zombie is when they straffe run now that is a pain in the arse, if that could be fixed it would be better i believe.
