Krampus has made an Infection, only Elfs can be infected by it, over time they will experience different symptoms.

Stages:

Stage 1: a rash appears around the bite mark. At this stage, amputating the limb can stop the infection.

Stage 2: fur starts growing on the Elf.

Stage 3: the Elf starts craving meat. amputating the limb at this point is useless.

Stage 4: they will grow claws and fangs.

Stage 5: they will grow horns, and their eyes will turn yellow, becoming a mini-Krampus

Stage 6: Unknown as they hide in the dark and most don't even go to this stage, but if you're in the dark, RUN. they will leave you alone if you have shelter.

Solders:

The Solders you team up with are Humans, as such the Infection don't affect them.

Solder Alpha: Cocky but skilled in both melee and range, believes himself to be the leader.

Solder Bravo: Self-centered but strong.

Solder Delta: goes off alone and barely talks yet has been known to kill large groups of enemies. Will always find shelter before night.

Solder Echo: Not that good with guns and puts himself before others but keeps multiple med kits on them at all times.

Solder Victor: You.
