Researchers at the University College of Southeast Norway are cruel people who like to play with the lives of lesser organisms.

They’re also kind of cool scientists who know how to have fun while researching microorganisms’ hunting habits.

The evidence for both these cases? A small game of Pac-Man set up by the scientists featuring real microscopic hunters and prey.

There are no power-up pills here, though, just a never-ending hunt to the death for the unicellular protozoa.

The researchers built and filmed the maze with the help of filmmaker Adam Bartley, who supplied the unedited footage above.

The Pac-Man maze has much more in common with the environments in which such organisms usually hunt than a petri dish, allowing for the observation of more life-like behaviors.
