Well CTs span as zombie when they die or get infected. If zombiez spawned as zombies after death it would be much harder for CTs.
Sounds like a good event idea to me
- but players would most likely hate it. If you knew how much heat we get when we add maps that are a bit zombie sided... on the other hand so many players love maps that are totally unfair towards zombiez. I guess players dont feel like winning the game if they win a round in team zombie.
