Blood Dungeon Arenas Hub

Blood Dungeon has six named survival arenas. Steam’s achievement spine lists them in this order: Catacombs, Pit, Corridor, Boiler, Tombs, Flood. The Daily Dungeon is extra (Play the Daily / Vampire Ring), not a seventh named stage. Each named map has its own hazards, enemy mix, and three bosses. Picking the right bunkmate for the map — Leggy in Flood, Bug in tight rooms, Skinja on open floors — matters as much as your weapon drops. The game launched 25 August 2026. Single-player only.

Start in Catacombs as Gun Man or Barbarian. Do not plan a “Leech run”; Leech is a Steam achievement (Wyrm in under 30 seconds), not a bunkmate. See Bunkmates and Achievements.

Named arenas

• Catacombs — first arena; learn walls, Blood, and Bones here
• Pit — next name on the achievement spine
• Corridor — chokes; gas and orbit weapons feel honest
• Boiler — industrial heat; second boss unlocks Hypnomancer
• Tombs — later spine name
• Flood — water; Leggy’s climbable webs are the published answer

Unlock chain

Public materials present the six names as a spine, not as a priced shop list. Play Catacombs until a second weapon slot and extra hearts make deaths rare, then step along Pit → Corridor → Boiler → Tombs → Flood. Boiler is the confirmed character gate: beat the second boss for Hypnomancer. This hub does not invent Bone costs for later maps. If the quest log names a different door, trust the log.

Daily Dungeon sits beside that spine. Clear it when the modifier matches a bunkmate you already own. It is not required to “unlock Flood.”

Arena-specific bunkmates

• Leggy in Flood — climbable webs in water. Other bunkmates still swim; she builds extra routes.
• Bug in tight rooms — flight skips floor piles. Corridor and industrial chokes reward leaving the ground.
• Skinja on open floors — shotgun, cartwheels, speed. Pit-style open space likes kiting.
• Hypnomancer in Boiler / Corridor — gas in chokes after you actually unlock him.
• Gun Man in Catacombs — machine gun teacher. Stay here until movement is readable.

Nine bunkmates exist; two names are unpublished. Do not invent a Flood-only secret character to fill a slot. Full kits: Bunkmates. Hedged ranks: Tier List.

Daily Dungeon

A rotating extra with bonus Bones. Play the Daily / Vampire Ring is the achievement language — treat it as a side mode, not map seven. Strategy: Daily Dungeon.

Progression

Early Bones come fastest from Catacombs knowledge, not from jumping to Flood undergeared. When slots and hearts exist, walk the spine. Boiler’s second boss is the Hypnomancer line. Flood is when water actually shows up — bring Leggy if she is unlocked, not a fictional whip character.
