Petri War is a microscopic auto-battle roguelite set inside a petri dish.
Start with a handful of cells and watch them feed, divide, mutate, and fight invading colonies.
Choose an evolution whenever your colony levels up, then watch new traits spread through offspring and neighboring cells.
Survive the dish to preserve genes and research new possibilities for the next generation.
You don't command individual cells—you create the colony that fights for you.
Mouse or touch: Select menus and evolution cards. Briefly click or tap the dish to make nearby allied cells avoid that spot. Repeated taps gradually weaken their response.
Space: Pause or resume. During a mutation scene, skip the scene.
1, 2, 3: Select an evolution card when available.
On-screen controls: Pause, change between 1×, 2×, and 4× speed, or toggle sound.
