NOCTILUCA

Carry the last light into the abyss.

You are a spark in a dungeon that forgot the sun. Descend through shifting, procedurally generated halls, claim relics, and burn back a dark that bites back.

NEW: The Drowned Crown update

• Three Vessels. The Lantern's rapid bolts, the Prism Witch's refracting beam that heats up and ricochets, and the Ember Knight's blades that cut enemy bullets out of the air.
• Lumen Surge. Kills fill a ring of light around you. Unleash Dawnburst, Spectrum or Sunfall.
• The Leviathan. A 23-segment serpent that dives beneath a flooded arena and erupts under your feet.
• Four new horrors. Phantoms that exist only in your light, Lantern Jellies, Mirrors that turn your shots against you, and Lurkers beneath the floor.
• Mythic Ascensions. Master two relics, become something more.

Also in the deep: 31 relics, 14 enemy types, named champions, Blood Shrines, volatile crystals, lightless rooms, three bosses (the Hollow Warden, the Leviathan and the Eclipse) and an endless descent after victory.
