Eh, don't see how the respawn idea would be helpful with escapes, even without the AFK killer. The run from spawn each respawn would be tedious and unhelpful.
Why can't we just reduce fast zombie health on escape maps using the same system Zero setup on the server? They're reduced 80% or more right now. Maybe pull it down lower? Perhaps far enough that a single P90 clip or 4-5 shotgun blasts would kill without headshots.
Can you edit the percentages on a per zombie class basis or is it applied across all equally, Zero?
