FIELD NOTE 01

Release, length and Demo answers

The official Steam Store displays Released 25 Aug, 2026, Buy Sludgineers and Add to Cart. Developer Andy Wiltshire estimates about four hours for the main game, then roughly two to three more hours for completionist play depending on strategy; the Game Length guide explains the approximate derived total and player corroboration.

The Demo is a separate secondary option. The official launch announcement says the full version adds a whole new map, progressively larger and more complex levels, new pollution, new quests, new and improved power-ups, many upgrades and abilities, refinery automation and drones.
