This page is a short overview of Hades: the biome order, the six weapons, the Mirror of Night, and notes on the Bone Hydra and the final fight. It is not a full run-by-run guide and does not cover every boon, keepsake or Pact of Punishment condition. The plot and biome order follow Wikipedia; weapon and Mirror details follow the Fextralife wiki.
Zagreus, son of Hades, tries to escape the Underworld to find his mother, Persephone. Each death sends him back to the House of Hades. Nyx helps him contact the Olympians, who grant boons. The four regions are Tartarus, Asphodel, Elysium and the Temple of Styx, and each unlocks after the previous one is cleared.
The Mirror of Night in Zagreus' room offers Talents, permanent passive bonuses that you unlock by spending Darkness (later ones also need Chthonic Keys). Shadow Presence raises damage against foes struck from behind, up to 5 ranks. Death Defiance restores half your health when you would die, one use per rank per run, up to 3 ranks.
You start with Stygius, the Stygian Blade. The other five are bought with Chthonic Keys at the Courtyard: Coronacht, the Heart-Seeking Bow (3 keys), Aegis, the Shield of Chaos (3), Varatha, the Eternal Spear (4), Malphon, the Twin Fists (8) and Exagryph, the Adamant Rail (8). Pick whichever fits the boons you are offered.
Tartarus is guarded by one or more of the Furies, and Asphodel ends with the Lernaean Hydra (Wikipedia). Both biomes introduce boon choices from the Olympian gods, which you stack across a run.
Elysium is guarded by Theseus and Asterius the Minotaur (Wikipedia).
Cerberus blocks the path to Hades in the Temple of Styx. You do not fight him. According to Gamepressure, you find a Satyr Snack (also called the Satyr Sack in some guides) in one of the temple's chambers and bring it to Cerberus, who then lets you through. Charon's shop in the central area is larger here, so you can make final purchases.
After defeating Hades, Zagreus reaches the surface and finds Persephone. He is bound to the Underworld, so he promises to keep escaping to visit her. Persephone later returns to her role as Queen of the Underworld, and Hades asks Zagreus to keep testing the Underworld's defences. The epilogue shows Persephone hosting a feast to reconcile with the Olympians, and Zagreus' escape attempts continue. Defeating Hades once also unlocks the Pact of Punishment, which adds optional difficulty conditions.
⚔️ Boss Guides
Lernaean Bone Hydra (Asphodel)
Attacks
According to the Fextralife wiki, the main head lunges, fires slow dart projectiles, ground-pounds and spits fire that leaves lingering lava. Extra heads add effects such as falling debris and waves. Smaller heads appear around the arena later in the fight, so you must track the main head and the smaller ones. Avoid the lava outside the arena.
Note
Sources disagree on the exact health thresholds and the number of extra heads, and one guide says it was written for the early access version, so check a current guide for details.
Hades (Temple of Styx)
Phase 1
According to Gamepressure, you must empty his health bar twice. He uses spear thrusts and wide spear spins, throws skulls that apply Boiling Blood (doubling the damage you take for a while) and leave explosive skulls on the ground, turns invisible and reappears with a big swing, and summons armoured minions while temporarily invincible.
Phase 2
His health bar fully regenerates. He fires energy beams that increase in number, summons vases that leave grasping stains, and uses spear swing series. Gamepressure notes that there is no single fixed strategy because it depends on your weapon, boons and upgrades.
