Moon Infection

(This is based on a Roblox game I suggest checking out, However I've made my own story here. The game is called "Moonlight Infection") You are trapped in a research facility in the Arctic after an unknown incident. The last rescue helicopter had landed, yet the crew vanished, The fuel tank was also fully empty. The infection turns humans into humanoid wolf creatures, basically werewolves. The transformation happens when the individual looks at the moon or has skin contact with moonlight for a long enough period. The ones already transformed can also turn others into wolf creatures if they bite for long enough. A blindfold can be worn to become immune from turning because of looking at the moon. There is also an area with a strange tree with large fruits. These fruits, when eaten, cause a feeling of warmth to spread through the person's body. The person will begin to feel weak and start sweating, before sprouting fur also becoming a wolf creature. In another area of the facility located inside of a cave, there are crystals. These crystals come in red, blue and purple. The crystals are so sharp that even touching them can cut you. When the crystal's shards enter the human body, they turn the person into a wolf creature with sparkling fur.
