Hades is a 2020 roguelike action role-playing game developed and published by Supergiant Games. It was released for macOS, Nintendo Switch, and Windows on September 17, 2020, following an early access release in December 2018. It was later released for PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X/S in August 2021, and was released for iOS in March 2024 through Netflix Games.

Players control Zagreus, the son of Hades, as he attempts to escape from the Underworld to reach Mount Olympus, at times aided by boons the other Olympians bestow on him. Each run contains a random series of rooms populated with enemies and rewards. The game features a hack and slash combat system; the player uses a combination of a main weapon attack, a special attack, a dash ability, and a magic ability to defeat enemies while avoiding damage to progress as far as possible. While Zagreus will often die, the player can use the treasure gained during runs to improve certain attributes or unlock new weapons and abilities to improve the chance of escaping on subsequent runs.

Hades was developed following Supergiant's Pyre, in which they wanted to explore procedural narrative storytelling. However, due to the nature of the gameplay, they found that players did not play through it multiple times to explore this. The roguelike structure of Hades allowed them to tell these branching stories to the player over the course of multiple playthroughs.

Hades has been cited among the greatest video games of all time, with critics praising its narrative, gameplay, art style, music, and voice acting. It sold more than a million copies and was named game of the year by several award ceremonies and media publications. A sequel, Hades II, was released in early access in 2024, and had its full release in 2025.

The player controls Zagreus, the prince of the Underworld, who seeks to escape the realm to get away from his unloving father, Hades, and reach his mother Persephone in the mortal world. Along his quest, the other Olympians support him, granting him gifts called Boons to help him fight the beings that guard the exit to the Underworld. He is also aided by notorious residents of the Underworld, such as Sisyphus, Eurydice, and Patroclus. The game world is divided between four main dungeons; Tartarus, Asphodel, Elysium, and the Temple of Styx, each representing one of the regions of the Underworld, with each new region being unlocked upon clearing the previous.

The game is presented in an isometric view, with the player controlling Zagreus. The player starts a run by fighting through several rooms drawn from a pool of pre-determined layouts, with the order they appear in and the enemies that appear being randomized. The game features a hack and slash combat system.

The player has a primary attack and a secondary "special" attack depending on their pre-determined weapon of choice, a magic "cast" that can be used from a distance, a dash that provides momentary intangibility and mobility, allows the player to phase through thin enough walls and gaps, and can deal damage when combined with an attack or Boon, and a summon attack that can call upon the power of one of the Gods. Throughout a run, the Olympians will provide Boons, each of which provides a choice of three persistent boosts and effects for that run that the player can select from. The Boons are themed based on the Olympian; for example, Zeus's Boons provide lightning damage effects and Poseidon's provide push-back wave effects.

The player moves through rooms to gradually ascend through the Underworld; after clearing a room, the player is given the room's rewards, allowing them to grow stronger or recover lost health points. However, if Zagreus' health points drop to zero while he has no "death defiance" tokens left, he is defeated and taken by the river Styx back to the House of Hades, which effectively acts as the game's overworld between attempts. Hades features a combination of roguelike and dungeon-crawler elements, where obols and certain types of upgrades are lost upon death and must be collected anew each time, while other types of currency can be used at the House to purchase permanent upgrades that affect future attempts. After clearing a certain number of rooms in a region, the player must fight the bosses of the region to advance to the next; at least one of the three Furies in Tartarus, the skeletonized Lernaean Hydra in Asphodel, Theseus and Asterius in Elysium, and Hades at the gates of the Underworld.
