About Infectious
Infectious puts you in control of a virus spreading through multiple organs in its host. You collect DNA to mutate, grow stronger and gain abilities, while outsmarting and outrunning the immune system. You can spawn viral clones to speed up your work and compete with other microorganisms to become the dominant pathogenic species.
Spread through the host
Explore a microscopic world at the cellular level and observe viruses overwhelming the host's body. Immune cells mimic real-life immune response behavior, so you must use upgrades and mutation abilities to gain an edge over the host's immune system. Chain infections let you earn incremental bonuses from your clones' work.
Virus types
You can unlock different types of viruses, each with its own abilities, including an alien-like virus that originated from space.
