Federation of American Scientists (FAS) makes a First-Person Shooter (FPS). Whoever wrote the description of the game won’t get a job at PC Gamer anytime soon, but the game itself looks interesting.

Players navigate a nanobot through a 3D environment of blood vessels and connective tissue in an attempt to save an ailing patient by retraining her non-functional immune cells. Along the way, students learn about the biological processes that enable macrophages and neutrophils – white blood cells – to detect and fight infections. A database of immunology facts is also included.
