Basically, think REPO or Leathal Company, but instead of money, you hunt Anomalies, like Siren Head, Slenderman or even Wendigos and Mothman, Stuff like Folklore and Mythical creatures. And its set in Post WW1 where the Clhorine gas makes a zombie apocalypse but its somewhat controlled. theres 5 classes: Juggernaut, Trapper, Marksman, Hunter and the MEDIC.

Abillities:

Juggernaut: Strong Melee (has a Zweihänder sword and a Mauser pistol) and tanks damage well.

Trapper: Sets up traps to slow down or immobolise Anomalies for a short time.

Marsman: Good with any type of Gun and has less reload speed and moves the fastest.

Hunter: Can identify in what direction the Anomaly went and can hide himself the best. (camo)

Medic: Heals and if a enemy comes too close he can release a bomb that makes the enemy halloucinate or sedate them for a short time.
