DirtyDan247 pretty sure thats only with custom FF loading like Jbleezy did in BO2 Reimagined Mod loading other weapon models, sounds and anims from singleplayer/mp to zombies.
chicken emoji yes, i use _zm_counters. (it gives a zombie counter) and perkaholic (gives all available perks on map). but i removed them and still only stamin-up machine spawned.
