Publisher Team17 announced on August 28 that Bossa Games is developing 'What Goes Up', a physics-based cooperative building game. It is scheduled for release later this year on PC, PS5, and Xbox Series X|S, and will also be available on PC and Xbox Game Pass. The trailer premiered during the 'XBOX @ gamescom Broadcast 2026' Day 2 stream on August 27. Players work as employees of the waste disposal company 'Galactic Refuse', dispatched to planets littered with garbage from Earth. The objective is to stack junk into designated structures within a time limit, using tools like a gravity gun, jetpack, and bounce pad. The game supports solo play and online co-op for up to four players. Hazards include lava rivers, high voltage, meteor showers, and incompetent colleagues, but fallen workers can be revived via a 3D printer. Bossa Games, formerly Bossa Studios, previously created physics-based titles like 'Surgeon Simulator' and 'I Am Bread'. The store page lists Japanese language support as planned in-game.
The reveal came with a trailer showing players cooperating to stack junk, riding furniture to cross cliffs, and suffering mishaps like being knocked out by thrown cars or frozen solid. The game's setting involves dangerous planets with materials such as hot dog stands, solar panels, and rusty bathtubs used for construction.
The tools provided by the company include a 'gravity gun' that can grab and throw objects, a 'jetpack' for reaching high places, and a 'bounce pad' that launches both junk and workers. Structures can collapse entirely if balance is lost, leaving players to decide between careful planning or haphazard stacking. Co-op play encourages dividing roles, but collapses lead to a 'blame game' among teammates.
Bossa Games, formerly known as Bossa Studios, has developed several physics-based games, including surgery sim 'Surgeon Simulator' and 'I Am Bread'. 'What Goes Up' is planned for release later this year on PC, PS5, and Xbox Series X|S, with Game Pass availability on PC and Xbox.
