Yeh the cool special looking things on these new zombies will even further showcase the lack of zombie diversity in game. It'd be cool if there were regular mundane zombies but when you see 50 soldiers coming at you and they all have the same vest tear and same exact guts bouncing around, it'll really highlight just how badly the game needs variants.
Don't get me wrong, they're cool looking AF, but I'm still right.
My *recommendation* would be to take a zombie, say the soldier, make ONE version and then have different children on the mesh have the variations, then on spawn roll a random number to decide which child is shown and which is hidden, so that you can have multiple variants using the same model. One child has the guts, another a bite wound, another a clothing tear, another a sidearm, another a rank insignia, etc... all hidden, then on spawn it decides which 1, 2 or 3 of those children get shown, and voila, instant variants.
I know this method already works, because science tells me so.
