Alien Parasite RPG

The alien parasite is a microscopic organism who's eggs fell to earth inside a meteorite. The parasite eggs remained dormant until they are in the intestines of a host. Once there, they will grow and multiply, releasing enzymes into the host's bloodstream put them in a state of constant hunger and turn their host's intestines into there home as they coat to the intestines tissue.

The alterations to alien parasites' host comes in two stages
•Stage 1: The alien parasites will put the host in a constant state of hunger, causing the host's to gain weight while also feeding the parasites as they multiply until they fully line the intestines and reach carrying capacity. At that point, Phase 2 begins.
•Phase 2: Phase 2 is when the alien parasites reach carrying capacity in their host and switch from reproducing asexually to reproducing sexually with the parasite population becoming either male or female. As they change, they release new enzymes into the host's bloodstream, which will cause the host to start craving raw meat and certain chemicals. At the same time, the host will start turning into a monsterous predatory creature to protect them. Once the mutations of Phase 2 are complete, the eggs of the parasites, ones that don't hatch out in the host's intestines, will migrate to the urinary tract and cling to sex cells of the host to start the cycle over in another host.
