Immunity

Immunity is a survival game in which you defend yourself against endless waves of bacteria. Use abilities such as Toxicity, Tracer and Energy Shield to fight until you can no longer continue. After each round, spend the gold you earn on power-ups for your next round.

Fight infected areas

The Infected Areas screen shows active and eradicated diseases in areas such as the brain, heart and stomach. You can purge the diseases found there. Enemies include Gingivalis Disease, along with symbiotic and viral entities that are faster and stronger than their lesser entities.

Power-ups

The in-game store offers Toxicity, Rocket, Tracer, Energy Shield and Super-shot power-ups to help you fight your foes.

Planned additions

The game’s planned additions include more diseases and areas to fight in, custom banners and titles, and dozens of Steam Achievements. White blood-cell upgrades such as Speed, Power and Rate of Fire are also planned, as is multiplayer in which players fight as either diseases or white blood-cells.
