room6 is set to release the puzzle adventure game UNDERGROUNDED on Steam on July 3, 2026, and has added the defense action game Thunder of the DemonKing to its publishing lineup.
room6 continues to build its publishing slate with distinctive indie titles. The most recent announcement, made alongside developer Game Studio, confirms that the puzzle adventure game UNDERGROUNDED will launch on Steam on July 3, 2026. The game follows Scott, a young man in Manhattan whose marriage proposal is rejected, as he descends into a labyrinth beneath the city. Dungeons are themed around American historical eras such as the film industry, space development, and the Wild West. Boss fights require players to play retro arcade games that pay homage to 1980s classics, and a cheerful canary companion offers hints. A soundtrack with 25 tracks inspired by 1960s and 1980s music will release the same day for 980 yen, and a demo is already available on Steam.
Earlier, at BitSummit PUNCH, room6 announced that Thunder of the DemonKing, developed by GoatGoatStudio, has joined its publishing lineup. The defense action game, which has been gaining attention through event demos and a Steam demo, was playable at the booth with two stages of the latest build. Players control a revived Demon King using lightning magic to fend off invading soldiers. Together, these two titles show room6's focus on quirky, accessible indie games with strong event presence and clear release plans.

room6 and Game Studio announced that the puzzle adventure game UNDERGROUNDED will launch on Steam on July 3, 2026, priced at 2,480 yen. The game follows Scott, a young man in Manhattan whose marriage proposal is rejected. He drops the engagement ring into a gutter and descends into a labyrinth beneath the city that condenses American history and culture. Players explore dungeons themed around the film industry, space development, the Wild West, and more. A cheerful canary companion offers hints when players are stuck. Bosses appear in the depths, and defeating them requires playing retro arcade games that pay homage to 1980s classics. Clearing these games alters the labyrinth and opens paths to victory. Scott also meets other characters who have lost something; helping them recover their lost items changes his own story. A soundtrack with 25 tracks inspired by 1960s and 1980s music will release on the same day for 980 yen, and a bundle set is planned. A demo is currently available on Steam.
