Atrox is a Radiated Planet in Astroneer.

Atrox has a choked atmosphere and very aggressive flora on its treacherous Terrain. Atrox's deadly flora includes Attactus, Spewflowers, and Wheezeweeds.

Small safe patches tend to form inside valleys between the steep plateaus. Glowing irradiated fog can be found hanging low to the surface, which despite its appearance, is harmless. Valuable Research items and Research Samples can be found on the planet, with the samples underground yielding upwards of 2500 Bytes.

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 Icon Hydrogen.png 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. It takes 30 units a sec to activate the gateway chamber.

    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 Generators or the RTG.
