About Infection X

Infection X is an arcade-style puzzle game in which you guide a virus through challenges, infect cells and collect RNA points. You must account for enemy behavior and use the mechanics of each puzzle to progress.

Puzzle types

Three kinds of puzzles take place in different parts of the body:

  • Pulmonary puzzles: navigate the branching airways of the lungs, fight antibodies, destroy white blood cells and overcome obstacles.
  • Cellular puzzles: use abilities such as inertia and jumping to reach a cell’s nucleus, with precise movement and timing needed to replicate within the cell.
  • Nuclear puzzles: move through a maze-like nucleus without touching its walls to reach the chromatin.

Enemies and boss

Enemies have different behaviors and present different challenges. A boss battle awaits at level 7.
