So when I put down respawn areas and play infection I naturally assumed that attackers would be zombies and defenders would be humans. Is this wrong? I never spawn in the respawn zones and I have no idea how to fix it. I have the height, width, and depth greater than zero so thats not a problem. Anybody know how these respawn areas work?
Did you set the respawn zones to be attackers and defenders? Better yet, just delete the respawn zones. In Infection games, when you set up the spawns, you have to set each respawn point to be an Attacker's or Defender's point. I know that's different from other gametype respawns, but for Infection, do not use any respawn zones. Just modify each respawn point. It's tedious, but that's the way Infection works.
As Awkward said, just place the spawn points, don't bother with areas. But you are correct; attackers are zombies, defenders human.
