From GameWatcher: "If there was any perk in Killing Floor 2 that needs an explanation, it's the Survivalist. Released to commemorate KF2's departure from Early Access in 2016, the Survivalist remains shrouded in mystique to many players. The perk is a closer, an archetype to fill any remaining holes in the game's roster. Having few unique abilities of its own, the Survivalist Skill-Tree takes mechanics from every other perk in the game- Allowing indecisive players to mix and match abilities, creating a completely unique class. The added freedom has its drawbacks: Survivalist cannot match or surpass the perks it mimics; I'd call it an understudy.
