Immunica
Become the immune system. Hover to kill. Weapons fire automatically. Manage your research lab, hire scientists, and develop a vaccine while fighting off endless pathogen hordes.
In Immunica, YOU are the immune system. Pathogens are flooding in. Your health is dropping. Every second counts.
Control the immune system from within. No clicking required. Just move, position, and watch the chaos unfold as your weapons automatically tear through waves of invaders.
ACTIVE SURVIVAL + IDLE PROGRESSION
Hover over enemies to deal damage. Your cursor is your primary weapon. Meanwhile, missiles lock on, beams fire, drones orbit, and burst pulses detonate around you. Focus on positioning while your arsenal handles the rest.
4 WEAPON SYSTEMS
Burst - AOE pulse centered on your cursor
Missiles - Homing projectiles that hunt down targets
Beam - High-damage laser for focused destruction
Drones - Orbiting allies that intercept incoming threats
FEVER MODE
Chain kills to build your Fever meter. When it fills, unleash devastating power: up to +500% damage across 5 escalating tiers. The more you kill, the stronger you become.
40+ PATHOGEN SPECIES
Face 8 pathogen types across multiple tiers. From tiny Prions to massive Helminths, each species brings unique behavior patterns. Every pathogen has 3 evolution levels: Normal, Mutant, and Alpha. Higher tiers mean deadlier enemies and greater rewards.
RESEARCH LAB
Between breaches, manage your own research laboratory. Collect pathogen samples from combat and assign them to your scientists. Hire interns, technicians, researchers, and senior scientists. Each has different processing speeds, efficiency rates, and capabilities. Watch your team analyze samples even while you are away. Progress continues offline for up to 8 hours.
Your goal: accumulate enough Vaccine Data to complete the cure.
