Immune System

Become an antibody. Defend the body. Blast every germ.

Immune System is a fast, colorful 2D arcade shoot ’em up from AshToy. Play as an antibody and twin-stick your way through waves of viruses, bacteria, and fungi before they overwhelm the body.

Move with one stick, aim with the other, and auto-fire as infections escalate across body-themed arenas. Grab shields, health boosts, and firepower upgrades mid-fight—then unlock stronger antibodies in the store to climb tougher levels.

• Twin-stick antibody combat with auto-fire
• Wave-based levels and escalating germ swarms
• Unlockable characters with unique stats
• Power-ups for shield, health, fire rate, and bullets
