Solo developer Miorama Games has released a free demo of Particle Collectotron, an active incremental game, on Steam, allowing players to experience the game's sci-fi particle reactor operation before its full release on 30 March 2027. The demo covers the first 30 to 45 minutes of gameplay, giving players a taste of the game's non-linear upgrade tree and experiment tuning features. In the full game, players will inject particles into the reactor chamber, harvest their energy, and upgrade the experiment to survive a "superinjection" that grows the reactor and adds another injector.
