Atrox is a Radiated Planet in Astroneer. It has a choked, greenish-yellow atmosphere with a surface that is made up of dark hills with luminous acorn-shaped rocks, deep yellow ravines, and shattered mountains, making it very difficult to traverse with rovers. Flora on and below the surface of Atrox is deadly, which includes Attactus, Spewflowers, and Wheezeweeds.

Atrox has the highest valued research items and research samples, with samples ranging from 70 Bytes on the surface, to 1,187 in the outer core, and research items giving as much as 14,400 Bytes.

Notable Resources[edit | edit source]

Atrox has no notable resources, however, four gases can be found on the planet.

Gases Parts Per Unit (PPU)
Helium 25 PPU
Methane 100 PPU
Nitrogen 50 PPU

Gateway Network[edit | edit source]

AstroWiki Warning.svg Spoiler Warning: Information below contains information that may ruin your enjoyment of discovering the game's secrets for yourself. Proceed at your own risk.
  • Atrox has six Gateway Chambers, each requiring 30U/s of power for 30 seconds to be activated. At least one must be activated before the player can access the Gateway Engine in the core of the planet.

    Once a Gateway Chamber has been activated, the Gateway Engine opens in the core. Placing a single Hydrogen in one of the slots reveals the Geometric Triptych. Placing the Geometric Triptych in the slot on the opposite side (above you) will activate the engine, revealing the Odd Stone and allowing teleportation to the core as well as revealing the inactive node for the Gateway Portal if it has not yet been discovered.

    Atrox is the only planet that requires an Atmospheric Resource to activate the Gateway Engine.

  • Notes[edit | edit source]

    • Since the planet has low wind and sunlight and an abundance of Organic sources, the best source for power would be Medium Generators or the RTG.
    • Atrox is the only planet that has Helium
    • Atrox is the only planet that requires a Gas to activate its core
