Solo developer Fist Pump Games has announced The Vessel for Steam. The 150-level puzzle adventure asks players to control two characters at once, with voiced dialogue and multiple story endings.
Every room in The Vessel requires two successful escapes. Solo developer Fist Pump Games has announced the puzzle adventure with a central rule: players control two characters at the same time and must guide both to the exit. The official trailer, published on ModDB on October 2, 2026, describes a puzzle adventure where the characters must work together to leave each room.
Two characters, one solution
The design changes how a room-based puzzle works. A move that helps one character can put the other in danger or leave them in the wrong position. Progress depends on timing and spatial planning for both figures.
According to the official The Vessel trailer on ModDB, the gameplay is built around timing, positioning and strategy after players solve a series of puzzles. This is more than switching between two heroes.
Simultaneous control can turn a familiar block puzzle into a coordination test. The Vessel treats the relationship between its characters as part of the puzzle. The second figure is not simply a passive companion or another viewpoint to switch to.
The official description puts it plainly: "control of two characters who must work together to reach the exit of each room." Paired coordination is the central rule of the game.
150 levels and changing mechanics
The announced campaign contains 150 puzzle-filled levels. Fist Pump Games lists blocks with different properties, timed doors, teleportation systems and other interactive elements among the tools used to vary the challenges. The mechanics described in the ModDB publication take the game beyond basic Sokoban-style object pushing by adding timing-based and spatial systems.
The numbers give a clear sense of the project's planned size: 150 levels and a mechanic list that goes beyond basic object pushing. They do not show how long the full game will take to finish. The announcement also does not explain how the difficulty will rise or whether every level will be available from the start.
The stated total still presents The Vessel as a full campaign-scale puzzle game, not a short experiment. Like the earlier MOLTYN coverage, this announcement offers a sharply defined gameplay idea while leaving release details open.
The available information identifies Steam as the platform through the game's store page. It does not provide a release date, price or edition structure. The available ModDB coverage confirms the public announcement and trailer, but it does not establish launch details beyond the Steam listing.
A mystery with multiple endings
The Vessel is not presented as a purely abstract puzzle collection. Its fantasy sci-fi story focuses on identity and self. Players investigate who the two characters are and where they came from.
Fully voiced dialogue is planned for a range of characters. The story will also have multiple endings. That gives the room-by-room structure a reason for repeat playthroughs, although the announcement does not explain which choices affect the outcomes or how many endings the game contains.
The link between the mechanics and the story is the project's strongest idea on paper. The puzzles ask players to understand the connection between two controllable figures. The story makes identity its central mystery.
Whether those ideas work together will depend on the level design and the finished writing. A feature list alone cannot answer that.
What players know
Fist Pump Games is an independent solo developer focused on distinctive gameplay systems and story-led worlds. The Vessel has been announced for Steam, and its trailer is available alongside the store page. The supplied announcement does not identify a launch date or confirm access beyond the listed PC storefront.
The October 2, 2026 ModDB trailer confirms the game's public presentation, its two-character structure and its stated 150-level scale.
There is no independent performance testing or review access to assess. The announcement discloses no resolution target, frame-rate target, system requirements, pricing or launch build details. The available evidence supports a feature overview, not a technical assessment or buying recommendation.
The available independent results also do not confirm a release date, price or platform details beyond Steam.
The Vessel has a clear proposition: 150 handcrafted puzzle rooms in which two characters must reach the exit together. That makes the announcement worth watching because the dual-character rule affects every part of play. It is not a cosmetic change added to a conventional adventure.
Simultaneous control means the core challenge is not simply finding one route. Players must maintain two valid routes at once. In practice, that can demand tighter planning than ordinary single-character puzzles because timing and positioning have to stay aligned.
The Vessel already has a clear design identity. Its unanswered release and technical details are why the announcement should be treated as a promising blueprint, not proof of a finished experience.
