Computer scientists from Italy's Politecnico di Milano created a set of AI-generated game designs that are so good that AI programs analyzing it pegged it as manmade. The team opted to experiment with legendary first-person shooter, DOOM. First released in 1993, DOOM has been a hotbed for experimentation. While the AI-generated DOOM runs on a standard computer, previously, people have figured out how to run the game on toasters, billboard trucks, calculators, and even thermostats. Scientists trained a Generative Adversarial Network (a model based on Artificial Neural Networks) to create new maps for the game.

The network uses two artificial intelligence algorithms, working both with and against each other.
