Unknown Disease
Unknown Disease is an intriguing sandbox simulation you can play instantly in your browser on mobile or PC. A very strange medical outbreak is sweeping through your neighborhood, causing incredibly lewd side effects for everyone infected. You have to figure out how this mysterious condition works, manage your own daily stats, and help treat the gorgeous women affected by the crisis.
This early build lays down a fantastic foundation, giving you the freedom to explore locations like the local hospital and a sketchy massage parlor. You will need to balance your time, earn some money, and track down love interests like Katie or Dr. Liza by following their personal schedules. It is a bit bare bones at the moment, but the core mechanics of managing your health and corruption levels make it super engaging.
If you are into management games with a steamy twist, you really need to give this demo a try and see the potential for yourself. The developer is actively expanding the storylines, so jumping in now means you get to watch the naughty chaos grow from the very beginning.
Press Play and start directly in your browser. Unknown Disease plays online on mobile and PC, with no download and no sign-up required.
