Corruption

the world has been corrupted, no one knows how it started. people have been turned zombie-like, only purple and black. the animals are almost worse, more aggressive and predatory than normal. there are few groups of people who have survived and not all are friendly towards outsiders. you have to make a group of your own by either finding lost people or joining other groups. you can scavenge, build, and hunt as you avoid being murdered by corrupted beings. you have any weapon that could be easily found or a makeshift weapon. weirdly, you can breathe inside buildings normally, just not outside. can you survive or will you be corrupted and killed? have fun!
