About Infectious

✦ AI summary

Infectious puts you in control of a virus spreading through a host's body, collecting DNA to mutate and spawn clones while evading the immune system and competing against rival pathogens. The game combines strategic gameplay with stunning microscopic visuals and real immune response mechanics, offering a unique perspective on cellular-level infection dynamics with diverse virus types and escalating abilities.

Take the role of a virus infecting multiple organs in your host. Outsmart and outrun the immune system. Collect DNA and use them to mutate, grow stronger and gain new abilities. Spawn viral clones to speed up your work. Compete with other microorganisms to be the dominant pathogenic species. And discover a beautiful microscopic world on a cellular level.

Game Features

Unlock different types of viruses (including an alien-like virus originated from space) with their own unique abilities.
Immune cells that mimic real-life immune response behavior.
Multiple upgrades and mutation abilities to give you an edge over your host's immune system.
Observe how viruses overwhelm the host's body on a cellular level.
Initiate chain reactions (in this case, chain infections) to gain incremental bonus from your clone's hard work.

The good news is that you don't need to be a microbiologist to enjoy this game!

INFECTIOUS is developed by a solo indie developer.

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Infectious features attractive designs and a fun premise about infecting a body, with gameplay that picks up once clone mechanics are introduced, though players note significant issues including AI problems with clones prioritizing wrong targets, stasis bubble glitches, and pacing problems in certain stages that detract from the experience. The game is seen as having a solid concept held back by execution problems, with one player suggesting it's worth playing if you have spare time and money but another dismissing it outright due to poor implementation.

Recommended Mar 11, 2026

A fun game about wreaking havoc in some poor guy's body. The first 2 worlds start slow, but things start picking up when you get clones to help. I do have a few complains though. 1. The clones are dumb, choosing to attack cells instead of the boss even when there's already enough numbers to win, 2. get stuck in stasis bubbles despite being freed previously, 3. the immune cells can attack your clones that are stuck in the stasis bubbles, and 4. the lymph channel stage is way too long. Other than that, yeah go ahead and get this game if you have money to spare and time to kill.

I've just realized the entire game is just a web browser in disguise But it does mean you can click F12 to mod the game which is amazing
