I'm sure this has been suggested before, but I'd love to see this. If experienced shooters die and zombify while gripping a gun, they could hang on to the gun and that muscle memory from a lifetime of shooting should prompt them to try to shoot their target, even as a zombie.
Gun zombies:
-rare
-very poor accuracy
-low rate of fire
-mostly military and cops
-run out of ammo and aren't clever enough to reload
-can only pull trigger, can't pump shotguns or rack bolt rifles
-keep pulling trigger even after hitting empty
-shoot rifles from the hip and pistols one-handed while shambling towards player, all with very poor stance
-will bite/scratch if you're close enough
-will shoot other zombies if they're in the way
-players can turn into these if they have high aim skill and zombify while holding a gun
Reasons to add this:
-it's fun
-adds MUCH needed enemy variety while keeping it grounded, without those crazy mutant zombie ideas
-makes guns more useful as you don't need to close the distance to take them out
-makes the first aid skill more useful and more level-able as there's more ways to get hurt without infection risk
-makes the rare bullet injuries more common, an injury type that currently doesn't exist outside of multiplayer PVP servers
-makes the great loot in police stations and army bases better guarded, as these have a higher chance to spawn there
-adds more challenge to the game, I'm sure a lot of people here find regular shambling zombies too nonthreatening yet find sprinters too threatening, this is a nice compromise
-finally a proper use for my bullet-proof vests
