Post what you want below. Heres my wishlist.
Juggernog: Take 5 hits before getting downed.
Pro version: When sprinting, zombies will fly out of the way. Obtained by taking 12 hits from zombies while using juggernog.
Speed Cola: Reload faster.
Pro version: Prime grenades, including Gersch devices and other grenades faster. Obtained by reloading while in close proximity to zombies 10 times.
PhD Flopper: Drop a mini-nuke when diving off an elevated area.
Pro version: Increased blast radius and damage of all explosions. Obtained by picking up 10 nuke power ups.
Quick Revive: Revive players faster.
Pro version: Revive players as fast as in multiplayer. Obtained by reviving the same player 3 times.
If a player dies after getting downed, any pro perks will be saved, but they will be downgraded to their regular versions.
I also think the Grim Reaper would make a good weapon in zombies.
