Hades 2 Complete Walkthrough: Underworld and Surface Route Clear Guide

This is the full walkthrough covering both routes in Hades 2. I have cleared both paths multiple times and this is the routing and decision-making framework I use. Not a room-by-room map (that would be impossible in a roguelite with randomized layouts), but the strategic choices that matter at each stage.

The Crossroads: Your Hub

Between every run, the Crossroads is where you spend resources and progress dialogue. Here is the optimal loop: clear a run (or die), then check the Cauldron for available incantations, talk to every NPC with a glowing dialogue icon, spend Darkness on Arcana cards, check the garden for harvestable reagents, visit the Wretched Broker to see his rotating inventory, equip your Keepsake for the next run, and go again.

Do not skip the NPC dialogue. I know it is tempting to rush into the next run, but dialogue triggers unlock: new Keepsakes, weapon Aspects, Cauldron recipes, the Surface route, and even the ability to romance certain characters. Every conversation moves something forward.

Underworld Route: Erebus (Biome 1)

Erebus is the tutorial biome in everything but name. The enemies are slow and their attacks are well-telegraphed. You fight Shamblers (basic melee enemies that swarm you), Wailers (ranged enemies that fire slow projectiles), and Skull-Crushers (large enemies that charge in a straight line and deal heavy damage if they connect).

Room routing: prioritize Hammer rooms above everything. After that, boon rooms from gods you want in your build. Gold rooms are third priority. Skip shops (Charon's wells) unless you have a lot of gold and need health, shop prices increase as you progress, so spending gold in biome one shops is inefficient.

There is always a Chaos gate somewhere in Erebus. If you find it and the curse is survivable, take it. An early Chaos blessing compounds over the entire run.

Boss prep for Hecate: enter with full health if possible. Use any fountain you find. If you have a Hex charged, save it for her phase two (the clone spawn).

Underworld Route: Oceanus (Biome 2)

Oceanus is a flooded temple with jellyfish enemies, eel-like creatures that burrow underground, and armored temple guardians with shields. The shield enemies are the priority target in every room, they block frontal attacks and protect nearby enemies.

The flooded sections slow your movement but not your dash. Sprint through water if you need to cross quickly, dash if you need i-frames.

Oceanus introduces miniboss rooms: tougher encounters that reward higher-rarity boons or double resources. The miniboss pool includes Charybdis (a whirlpool monster that creates suction zones), armored Shambler variants, and wave defense rooms where you survive against spawning enemies for a set duration.

Between Oceanus and the Mourning Fields, you hit a transition room where you can swap Keepsakes. This is when you should switch from a god Keepsake (if you were forcing a specific god) to the Coin Purse or Cerberus's Collar. You have your core boons by now, focus on survivability.

Underworld Route: Mourning Fields (Biome 3)

The difficulty spike. Enemies here are faster, more aggressive, and hit about 40 percent harder than anything in Oceanus. The Fields introduce Wraiths (ghost enemies that phase through walls and attack from unexpected angles), Mourners (slow-moving enemies that emit a damage aura around them), and Elite Shambler variants with extra health and damage.

The open room layouts mean you cannot funnel enemies into chokepoints like in Oceanus. Stay mobile. This is the biome where Sprint becomes your best friend, dash for i-frames, sprint for repositioning.

There is a hidden fountain room in the Fields. Look for a door marked with a weeping statue icon, it leads to a room with a healing fountain and sometimes a Chaos gate. This fountain has saved countless runs.

Cerberus boss prep: you want at least two death defiances available. If you only have one, prioritize fountain rooms and buy healing from Charon's shop before the boss door. Demeter's Frost is extremely valuable for this fight (freezing one head at a time simplifies the chaos dramatically).

Underworld Route: Tartarus (Biome 4)

Final biome. Tartarus is a series of small, cramped rooms with high-density enemy spawns. The enemies here are the hardest non-boss encounters in the game: Titan Sentinels (giant armored enemies with sweeping attacks), Time Wisps (fast-moving enemies that slow you on hit), and Chronos's Chosen (elite variants of earlier enemies with extra attack patterns).

The room layouts in Tartarus are claustrophobic, which makes crowd-control boons (Zeus chain lightning, Poseidon knockback, Hestia fire trails) extremely effective. Single-target builds struggle here because there are always 5-plus enemies on screen.

Chronos boss prep: this is the run-defining fight. Enter with the Acorn Keepsake equipped (absorbs boss hits). Save your Hex for phase three (the duplicate charge wave). If you have a Chaos blessing that increases damage dealt or reduces damage taken, the Chronos fight is when it pays off most.

The fight itself: destroy hourglasses in phase two IMMEDIATELY. Sprint through the scythe sweep, do not dash away from it. Focus on survival in phase three, let Scorch or Frost ticks do damage while you dodge. It is not a speed kill fight. Patience wins.

Surface Route: Ephyra (Biome 1)

Unlocked via Cauldron incantation after several Underworld runs. Ephyra is a ruined city with human enemies (City Guards with shields, Trappers that place ground hazards, and Archers that fire from elevated positions).

The shield guards require you to attack from behind or use attacks that pierce shields (Omega Cast zones, certain boon effects like Zeus chain lightning). The traps on the ground are visible before they activate, glowing red circles that detonate after a delay. Sprint out of them.

Ephyra has fewer rooms than Erebus, which means fewer boon opportunities. Your build will be less developed for the Chimera fight than it was for Hecate. Compensate with Chaos gates (take every one you find) and buy boons from Charon's shop if you have the gold.

Surface Route: Thessaly (Biome 2)

Mountain pass with crumbling platforms, high winds, and the Storm Giant boss at the end. The wind pushes you in a random direction periodically, which is annoying but predictable (it gusts every 8-10 seconds).

The crumbling platforms are the real danger. When the floor cracks (visual tell: spiderweb cracks spreading from the center), move to a stable platform within 3 seconds or fall to your death. The platforms regenerate after about 30 seconds, but in a boss fight, you might not have that long.

Poseidon boons gain value here because knockback can push enemies off cliffs for instant kills. Poseidon's dash makes you immune to the wind push effect (the dash overrides the wind physics).

Storm Giant prep: Black Coat trivializes this fight (shield absorbs lightning). If you do not have the Coat, bring the Acorn Keepsake and prioritize not dying over dealing damage. The Giant's health pool is large but his attacks are survivable if you focus entirely on dodging.

Surface Route: Mount Olympus (Biome 3)

The final Surface biome and the hardest area in the game. The enemies are divine guardians with complex attack patterns, high health, and the ability to buff each other. Olympus introduces Priest enemies that heal nearby allies, kill these first in every room, no exceptions.

The rooms are beautiful (Supergiant knocked the art direction out of the park here) but mechanically punishing. Narrow bridges, falling debris, and enemy compositions designed to corner you. Sprint is essential, standing still for more than a second gets you swarmed.

Final boss prep: enter with everything. Two death defiances minimum, a fully charged Hex, the Acorn Keepsake, and a build that can handle both crowd control and single-target damage. If you used resources on the Storm Giant and arrive depleted... consider whether this run is the one or whether you should treat it as a farming run for future attempts.

General Routing Principles

Hammer rooms are always the highest priority. After that, boon rooms from gods you want. Then resource rooms (gold, health, pomegranates). Shops are lowest priority unless you specifically need healing or a boon purchase.

Miniboss rooms are worth the risk. The double reward plus a chance at a Rare or better boon makes them higher value than normal encounter rooms.

Fountain rooms (healing) appear once per biome in fixed locations. Knowing where they spawn (Erebus: usually 4-5 rooms before Hecate. Oceanus: mid-biome, near a flooded section. Mourning Fields: the hidden weeping statue door. Tartarus: 3 rooms before Chronos) lets you save healing for the optimal moment.

Between every biome, swap your Keepsake. God Keepsake in biome one (force core boon). Utility Keepsake in biome two (gold, health). Combat Keepsake for the boss (Acorn or Skull Earring). This rotation is the single biggest factor in run consistency that most players overlook.
