Dungeon Lurker

Dungeon Lurker is in development at 13AM Games for PC via Steam, with a demo available and more than 100,000 wishlist registrations. The studio showed the game at its Tokyo Game Show 2026 booth at Makuhari Messe.

Synthesized from 5 Yomimono stories · updated Sep 20

13AM Games announced Dungeon Lurker in June 2026 as a horror action roguelike for PC via Steam, with a release date undecided and Japanese language support not planned. Two months later the studio released a demo alongside a new trailer. By late August the game had passed 100,000 wishlist registrations on Steam, with the demo still live. A September hands-on report described the studio's central design decision: an instruction manual with handwritten notes from a previous owner, carrying a shortcut route and circled enemy weak points, so the fiction lives in the printed material rather than in cutscenes.

The stories agree on the broad shape. The player controls a knight searching a cursed dungeon for a missing brother, with immortality promised at the deepest level, across more than 30 stages. Combat allows launching enemies into the air with a sword, shield guards, dodges, spells, and passive skills. The demo includes a pause-menu manual that the player can read, which the coverage treats as the game's distinguishing feature.

Details shift as the game is shown. The earliest announcement describes 32-bit visuals and a narrative about exploring a deceased friend's belongings. Later stories specify a fictional console called the Eclipse System 32, then the Eclipse System 32, and a structure of three areas and 15 floors. The August hands-on says 15 floors; the August 5 story says over 30 stages. The Tokyo Game Show 2026 booth, which opened at Makuhari Messe on September 17, presented the three-area, 15-floor structure directly to attendees.
