Immunity is a fast-paced survival game where your body becomes the battlefield.
Play as different immune cells, each with their own strengths, abilities, and playstyles, as you fight through waves of bacteria, viruses, and other threats. Every run pushes you to adapt, choose new mutations, and build a stronger defense before the infection overwhelms the organ you are trying to protect.
As you survive, you will collect DNA, unlock new immune cells, and experiment with different combinations of abilities and upgrades. Some builds focus on clearing large groups of enemies, while others reward speed, durability, or carefully controlling the battlefield.
The longer you survive, the more intense the infection becomes. Enemies grow stronger, pressure builds, and protecting both yourself and the surrounding tissue becomes increasingly difficult.
Features:
Fast, replayable survival runs
Multiple immune cells with distinct playstyles
Mutation choices that shape each build
Enemies that attack both you and vital organ nodes
Permanent DNA progression and character unlocks
Increasing difficulty that keeps every run tense
A biological theme built around the immune system
Fight the infection, evolve your defenses, and keep the body alive.
