Trigon: Space Story is a space RPG where players traverse a galaxy made by developer Sernur.Tech. The developer has been very open about the gameplay but has been mostly tight-lipped regarding multiplayer modes.
Does Trigon: Space Story offer multiplayer modes?
There are no plans to make any multiplayer modes available, and the game is a single-player experience. The developer is solely focused on making a game with a story. They have not made any announcements that they will add multiplayer functionality.
Steam forums for the game are filled with requests for multiplayer, but the developer has not responded to any requests for modes. Having a mode involving two players would take much more time and effort, and the developer is already close to completion and will move on to DLC.
From what we've seen of the demo, it looks like it would only really support player versus player battles. The game would be fun, but the mouse is required for combat, and that would present its own set of challenges.
