Synthesized from 4 Yomimono stories · updated Jul 3

Mouthwashing, the narrative horror game from developer Wrong Organ, has seen a modest but notable expansion into merchandise and bundling since its release. Good Smile Company announced two figures in mid-2026: a POP UP PARADE Swacchao! figure of the character Curly, scheduled for December 2026 at 4,800 yen, and a Nendoroid of mechanic Daisuke, also releasing in December 2026 for 6,800 yen. The Curly figure depicts the character wrapped in bandages with glaring eyes and exposed teeth, and its package is a special specification that allows buyers to craft a chair for the figure, referencing a key object from the game. The Daisuke Nendoroid includes smiling, serious, and bloody face plates, plus a party hat, cocktail, and workshop background sheet.

In May 2026, Fanatical included Mouthwashing in its Into Games Charity Bundle 2026, a set of 11 PC game keys priced at 2,630 yen that also featured titles such as CloverPit and Monument Valley 3. The bundle ran until June 25. Meanwhile, Wrong Organ announced its next title, Carcass Clad, during the PC Gaming Show 2026 on June 8. That game is a three-player online cooperative horror title set in the city of Volgorod, with players taking on distinct tank crew roles. Carcass Clad is in development for PC via Steam, with no release date set. The announcement marks a genre shift for the studio, which built its reputation on the psychological horror of Mouthwashing and How Fish Is Made.

Wrong Organ Announces Co-op Tank Horror Game Carcass Clad

Wrong Organ, the developer behind the acclaimed horror games Mouthwashing and How Fish Is Made, announced its next title, Carcass Clad, during the PC Gaming Show 2026 on June 8. The game is a three-player online cooperative horror title set in the city of Volgorod. Players take on the roles of a tank crew-commander Kanerva, gunner Erkki, and driver Taisto-each with distinct responsibilities. The commander uses a periscope to spot targets and listens to radio chatter to plot safe routes. The gunner loads, aims, and fires the tank's 158mm cannon, processes scavenged materials, and refuels. The driver manages fuel consumption, power distribution, and must stop at precise moments for accurate shooting. Enemies are described as mechanical shells decorated with carcasses as part of a ritual. Each session lasts two to three hours. Carcass Clad is in development for PC via Steam, with no release date set. The store page indicates Japanese display support is expected.
