I have to give a applause to jimmy zielinski because he really cooked with how he handled special zombies.
Instead of making them just a beefy enemy that just attacked the player, each one of them has certain mechanics that made them more unique.
George A. Romero stalking the player and if you damage him enough, he will drop you a perk powerup so you can get all the perks in the map and also if you completed the easter egg, you can get the wunderwaffe DG2 (Such a nice detail)
We all know how annoying the space monkeys can be in ascension but i still appreciate the effort of taking the risk of making something be different and special (But in solo, they are impossible to handle so yeah… thats bad)
All the special zombies in shangri la (Monkey, Shrieker and the napalm zombie) are a very nice addition, each one of them presenting a different challenge but i love how you can use them in your favor (You can get any power up you want with the monkeys, If you headshot a shrieker, it instantly kills all the surrounding zombies, Napalms can be a little more tricky)
And finally, the astronaut is also a stalker type enemy but its pretty slow, but if it gets you, it takes a perk from you.
