Idle Plague is a simulation game developed by Iron Horse Games LLC for Android platforms. The game takes you on a journey through the eyes of a microbe, where you spread the plague from organ to organ and infect hosts one by one while fighting immune bosses, antibodies, and white cells. The game features beautiful 3D low poly organs and allows you to recruit fellow microbes such as bacteria, viruses, and more to help you spread the plague.

In Idle Plague, you can upgrade your microbes, viruses, and bacteria to produce toxins and spread the plague to hosts one by one. The game also allows you to unlock organs and explore idle gameplay. You can mutate your idle microbes to evolve and fuse idle plague bacteria to create new microbes. Additionally, you can fight immune bosses for special gifts, participate in addictive “Microbe Ranger” events for more idle plague, and evolve special boosters. The game boasts of a fun idle plague tapper and beautiful hand-crafted 3D low-poly idle gameplay, inspired by real organs, bacteria, viruses, and microbes.
