Armicro

Armicro is a real-time strategy game where you play the immune system of one host. An infection spreads, taking over healthy cells and sends waves of pathogens at you, getting stronger as it goes. From your Lymph Node you spawn immune cells, harvest glucose from healthy tissue, and claim outposts to grow your economy. When you first spot a pathogen, your strongest adaptive cells unlock. Destroy the infection, or kill the Virulent Virion boss, before it overruns your Lymph Node.

Matches take 10–15 minutes, it's built for players aged 12+, and it runs on PC, Android and web.
