Happy Volcano and Oro Interactive announced Grave Mistakes on October 1, 2026. The online co-op horror comedy is scheduled for release on Steam in 2026, with a playtest and wishlist sign-ups open on the store page. Two to four players run the Good Mourning Funeral Home, handling grieving families, preparing services, delivering eulogies, playing the organ, and processing bodies. The funeral home has a back-room job: while one player reads a eulogy in front of the bereaved, another cuts and washes bodies in the back yard. Bodies rot over time, so speed matters, and players can replace an arm with a shovel or a leg with a skateboard. A Grandma is locked in the basement and demands a specific body part as food each day. If the part is not ready by day's end, one player may become that night's menu. Proximity voice chat is supported, and the funeral home can be upgraded.
Oro Interactive opened the Steam store page for Grave Mistakes on October 2, 2026, a day after the announcement. The co-op action game is developed by Happy Volcano, the studio behind the project, and is set for a PC release on Steam in November 2026. Playtest sign-ups are open now.
The funeral home is named Good Mourning Funeral Home. Players divide duties between the public ceremony and the back room: decorating the body, reading eulogies, playing the organ, and handling grieving families on one side, and dismembering and cleaning corpses driven by physics simulation on the other. Bodies rot over time, so processing them quickly is part of the loop. Limbs can be swapped for other objects, including a shovel for an arm and a skateboard for a leg. The bereaved family's suspicion must be kept down while the necessary parts are secured.
The proprietor, Grandma, is locked in the basement and demands a specific body part as food every day. Failing to prepare that part by the end of the day can result in one of the players becoming that night's menu. The game supports online co-op with proximity voice chat and includes upgrades and improvements to the funeral home itself.
