Our take on Systematic Immunity

The defining constraint is that each white blood cell can eliminate only one germ. That turns every casualty into a lasting tactical cost while the team moves through the infected body.

What is Systematic Immunity?

Systematic Immunity is a precision platformer set within an infected human body.

A team of 20 white blood cells must move through hostile tissue while stopping a germ that is producing more germs. Movement includes running, jumping, rolling, floating, bouncing, and teleportation. Each cell can eliminate only one germ, making casualties part of the challenge. The game contains 75 levels across three organs, with a boss germ in each organ. Collectible information snippets cover the human immune system and biology. Additional levels can be unlocked, each with its own information snippets. A level editor allows custom stages to be created, played, and shared. Controls support keyboard input and Xbox 360 or Xbox One controllers.

How Systematic Immunity plays
