Hades is a roguelike action role-playing video game developed and published by Supergiant Games. Players control Zagreus, the son of Hades, as he attempts to escape from Underworld to reach Mount Olympus, at times aided by gifts bestowed on him from the other Olympians. Each run challenges the player through a random series of rooms populated with enemies and rewards. The game has a hack and slash combat system; the player uses a combination of their main weapon attack, dash power, and magic ability to defeat them while avoiding damage to progress as far as possible. While Zagreus will often die, the player can use gained treasure to improve certain attributes or unlock new weapons and abilities to improve chances of escaping on subsequent runs. https://en.wikipedia.org/wiki/Hades_(video_game)
