This is the real game, playing itself.
Two AI teams fight on a loop below — the same engine you play. Shots ride the blood flow, bounce off taut tissue, carve craters in the floating clots and fling bacteria across the organ.
Pick a squad. Merge your cards. Make it fly.
Pick 3 bacteria
Four real-world microbes, each with six signature cards. All three stand on the field at once — choose a card and you choose who acts.
Draw 5 · merge pairs
Every turn: five cards, three AP. Two copies of a card merge for free into a stronger one — but it costs more to play. Bank it, or spend now?
Aim · fire · fling
Hold to charge, release to fire. Bank off taut walls for +40%, swim up onto clots, and bat the immune system clean off its perch.
Not just damage. Blast, dig and fling.
Every weapon is a different action — a homing spore, a crawling culture, an ulcer that ruptures the wall overhead, a wall you grow, a clot that waits. Each card shows how big it blows, how deep it digs, and how far it throws.
