space you helped develop the pack
there's only five things that can possibly do this (that is, kill you instantly), and half of them are single use- the other half is only at point-blank
Every time I went and fixed things I tried to reduce the damage somewhat e.g. the shotguns took two shots on players but only one on zombies depending on which mods are enabled. Then you went and removed that and have them all instant kills.
Most of them aren't point-blank only. The combat shotgun kills anyone at massive distances due to the tiny spread and rapid fire making it better than the Battle Rifle at range due to volume of shots, and the Bullpup is pretty much a sniper rifle when used right. Also the hitscan headshotting sniper rifle you had on your server.
