So whenever you are turned into a Romeral Zombie you are basically just a Walker from TWD, that is mega boring though and it is sometimes cool it would be fun to add special infected like in Left 4 Dead and it would depend on races/mutations.
Some abilities would be defaulted based on your race, like say a Lizard gets infected they would have certain abilities and traits like being resistant to fire, or doing more melee damage because of their claws or something but you would also be able to mutate other traits based on how many people you eat or something like say you kill 2 people you would have 2 points to evolve.
You could also mutate based on stuff that was effecting you before you got turned into a zomboi. Like say you had the strength mutation from genetics you would turn into a supa strong zombie, or if you had a microbomb implant you would be able to suicide bomb people stuff like that and most of the genetics traits would make you into a special zombie.
So overall I think the Romeral zombie outbreak is dumb and each time it happens the round is super short. So maybe you could make this into another gamemode or something and keep the whole Romeral thingy the same but make another gamemode for this idea but I like the whole zombie idea it is just bland and boring generic zombies.
