Maybe have cyberzombies be aggressive towards regular zombies, as if they notice their augments make them better than their all-flesh counterparts? Would make for a more apocalyptic look that could be good for post-apocalyptic modpacks or just for that extra zombie-killing mayhem.

I wish someone would work on that SCP mod again. We need the clockwork virus back in later versions of Minecraft.

Divinespect. They should prioritize villagers (turning them into zombies) and then go after regular zombies if there are no more villagers. (Maybe changing it to a percent chance that a defeated zombie turns into a cyberzombie. 35%? Might actually make it harder to get parts since they'll be taking damage, but not guaranteeing that they'll have something there to replace them should they win.)

Oops. Prioritize villagers and players. Then zombies.

Interesting idea - not sure how I feel about it. Could potentially add a config option, though I'm not sure if it makes sense to be enabled by default.

Damned Cybermen. Lol.

That would be funny. If a cyber zombie beats a regular zombie, then it makes another cyberzombie. Lol

I second both those notions :D that would make it possible to convert zombies from spawners into cyber zombies

Which would make farming Cyberzombies too easy. Maybe a contagious variation which doesn't drop cyberware.

What if the contagion rate was stunningly low and they could only drop some basic stuff, perhaps instead of implants, drop components

Then you'd have anti zombie guards which can lower the threat from vanilla zombies.

Ups, sorry, meant to say that instead of simply aggroing vanilla zombies, they could instead have an area effect that had a low chance of turning surrounding zombies into lesser cyber zombies
