“The Last of Us” survival
It is basically Zombie Infection, except the longer you survive without getting killed, you evolve. Though that could encourage the Infected to camp until they’re the Bloater. Anyways, just an idea.
Runner - Start off as (Makes lot of noise, low health, pretty fast)
Stalker - If you survive for at least 3 minuets (Doesn’t make much noise, Decent health, pretty fast)
Clicker - Survive 7 Minuets (Makes a good amount of noise, Amazing Health, Normal Speed, CAN’T SEE < Idk how that would work though.)
Bloater - Survive 13+ Minuets (Makes lot of noise, Legendary Health, Slow/Normal Speed, Can’t see?, Can use ranged attack, can kill players without re-animating them < That would actually be really cool imo)
