A virus is attacking your cells, and its up to you to defend them! Buy and combine cells to assemble your immune response. Discover powerful synergies to overcome a constantly evolving enemy in this physics-based auto battler. Outlast your opponents or work together to achieve IMMUNITY.

Create the ultimate immune response: Combine immune cells in interesting ways to overcome incoming pathogens. Merging the same immune cells together will strengthen them and can unlock higher tier immune cells to experiment with. Chaining different cells together can reveal powerful synergies.

Adapt or die: Viruses that successfully infect your cells will multiply and become an even bigger threat. You’ll adapt to the current situation and form the best defense given limited resources
