Astroneer is a sandbox exploration game where you reshape alien planets by hand. The terrain deforms like clay—dig tunnels, flatten landing pads, or carve out underground bases directly. You'll gather resources, build modular structures, and set up automated production chains to craft tools and vehicles. Exploration spans multiple planets, each with distinct biomes and materials. The game supports solo play or co-op with friends. Resource management matters: oxygen tethers keep you alive on the surface, and you'll need to plan supply lines as you venture farther from base. No combat—the challenge comes from environmental hazards, power management, and figuring out complex crafting recipes. Works well if you like freeform building with tangible goals rather than pure creative mode.
