I think i’ve read something about it but i can’t find it back.
What about circus ? It would fit well with DDA and CZS, and gives the oportunity to add some strange animals (and mutated ones in DDA). Elefant, lion, big snakes, girafe, horse…
Also new zombies : clowns (can throw several knife in one attack, can move on a big ball…), acrobates (fast, can climb like the Parkour perk, special move like martial arts…), fire throwers (can spread fire)…
More, we could mount. Horse, but also other kind of animals. So new items, like saddles, horse food… They smell but they are usefull to go faster in the forest for example, and swim, and ultimatly, they are food…
