For one of my new infection maps,roof top run, i am having zombies spawn either on the ground of crypt as normal zombies or on platforms higher up in crypt, holding weapons to make them special zombies. My question is assuming nobody in the zombie spawn room dies, and no enemy can come close to the room, would spawning be entirely based on the number of spawn points or would some other factors be involved that I don't see right now? thanks for you help.
