Confirmed elements
Crafting is one of Light No Fire's core gameplay pillars, alongside adventure, building, and exploration. The official Steam page describes players gathering resources across different biomes to create equipment, tools, shelters, and gear.
The reveal trailer shows structures built from wood and stone. There are no visible high-tech materials, metal plating, or industrial construction. Everything looks hand-built and medieval, which fits the fantasy setting. You will not be manufacturing laser cannons here.
Boat building
Sean Murray confirmed during the No Man's Sky Voyagers update (August 2025) that the ship-building technology carries directly into Light No Fire. In No Man's Sky, Voyagers lets players construct walkable ships room by room, with interior spaces like med-bays and sleeping quarters.
For Light No Fire, this same system powers boat construction. Murray described "real oceans to traverse, needing large boats and crews," which means crafting boats is not optional but necessary for ocean crossings.
Fantasy materials
The game replaces No Man's Sky's sci-fi technology with low-tech weapons and magic. The crafting system likely follows suit: expect wood, stone, animal parts, herbs, and potentially magical components rather than alloys and circuit boards. Trailer footage shows glowing weapons that appear magically enhanced, suggesting some form of enchanting or imbuing within the crafting system.
Different biomes contain different resources, so crafting is tied directly to exploration. You cannot stay in one location and access every material. The Earth-sized planet means some rare resources might require long expeditions to reach.
