SteamAbout Cell Defense
Cell Defense is an incremental tower defense set inside the body. You command a single antibody at the center of the cell while viruses, bacteria, and mutating swarms pour in from every side. Survive, bank what you earn, and pour it into weapons, cards, and upgrades that shape your build and push the next run further than the last.
Survive, earn, repeat
Plan a build, start a run, and collect the rewards when your cell finally falls. Early runs keep your hands on the controls: you're buying upgrades mid-fight and reacting to the swarm. Later, idle income and higher game speeds let runs play out on their own and keep paying while you're away.
Draft a build that fights your way
Weapons, cards, and upgrades snap together into builds that are yours and a fresh draft after every run means there's always a new one to chase.
Push deeper
The waves never stop. A boss arrives every ten of them, difficulty tiers raise both the danger and the payout, and game speed scales up to 5×. There's always one more wall to break.
