Mycopsychosys!

so, its night, and a spore storm has came towards your country. a single apore can infect a human, stage 1, feeling sick and social, stage 2, more social and attention wanting, stage 3 wanting to go to a higher place, stage 4, the blooming. you grow mushrooms on you, and if your around a bloomed person you can get infected within 30s. heat of around 100-150° can kill a spore. so does with freezing, intro: you get a call from your new neighbor who is new to spore storms, a guy in your basement wanting to get inside the house, and a guy wanting to "sell" a product. but the spores cant go through water. have fun! (the real thing is a game, if you dont know thats fine but id heavily reccomend playing it.)
