Schedule 1 released v0.4.2 open beta update on Steam on December 22, 2025 for PC. The update plants a surprising number of fungus-related systems into the game alongside quality of life improvements, visual tweaks, and a stack of bug fixes.
The biggest additions center on mushroom gameplay. Players will find new items such as shrooms, a mushroom bed and spawn station, substrate and spawn, visual effects, a new NPC friend called Fungal Phil, and a mushroom introduction quest. The update also adds a temperature system with a heatmap display, an AC unit, a units toggle for imperial and metric, and a renaming feature for management objects.
