About ASTRONEER

Astroneer puts players in the role of space‑faring pioneers tasked with exploring a seven‑planet system. Survival hinges on creativity, as the Terrain Tool lets you reshape ground, harvest resources, and add colour to the landscape.

Basebuilding uses a snap‑together modular system for power plants, harvesters, railways and more. You can play alone, invite friends into your world, or join a 2‑4 player online co‑op session, with full controller support and Steam Cloud saving.

01 / THE GUIDE

Terrain Tool

The Terrain Tool is described as a powerful instrument that can dig, collect, shape, build, and colour terrain in any way Astroneers wish. It works on any surface, from the planet’s crust down to its core, letting players modify the environment as needed.

Because the tool also applies colour, players can mark paths, differentiate structures, or highlight resource veins. This flexibility makes it central to both resource gathering and creative construction across all celestial bodies.

  • Use the digging function early to expose hidden resource veins.
  • Apply colour to distinguish functional zones in large bases.

02 / THE GUIDE

Basebuilding

Bases are assembled from modular objects that snap into place, allowing unique designs. Players can construct automation systems, crafting stations, power plants, resource harvesters, and railway facilities from the ground up.

Each component can be customized to suit the specific challenges of a planet’s geography or biome, supporting survival and expansion wherever you land.

  • Start with a power plant to ensure a steady energy supply.
  • Connect harvesters to storage units via railways for efficient resource transport.

03 / THE GUIDE

Solar System Exploration

The game features seven distinct celestial bodies, each fully explorable from the rounded surface all the way down into the core. Every world presents unique geography and challenging biomes that require adaptation.

Exploring these planets reveals varied resources and environmental hazards, encouraging players to tailor their equipment and bases to each location’s demands.

  • Map out terrain features before committing to large constructions.
  • Carry a portable power source when venturing into deep caves.

04 / THE GUIDE

Mysteries and Artifacts

Strange structures and artifacts dot the worlds, accompanied by confusing communications from unknown sources. Investigating these anomalies can reveal hidden lore about the solar system.

These discoveries are optional but provide additional objectives for curious Astroneers seeking deeper engagement with the game's narrative.

  • Record the locations of unusual structures for later study.
  • Bring extra storage when approaching artifact sites to collect any items you find.

05 / THE GUIDE

Multiplayer Co‑op

Astroneer supports solo play and 2‑4 player online co‑op. Friends can drop in and out of a world at any time, offering flexible collaboration without interrupting progress.

Full controller support, DualShock compatibility, Steam Cloud, and remote play on tablets or TVs ensure a seamless experience across devices.

  • Coordinate base layouts with teammates to avoid overlapping structures.
  • Use remote play on a tablet for quick check‑ins while away from the main PC.
