Where to get the Atropian Blade (melee weapon)

The melee upgrade is in biome 1, behind a sealed gate. Here is the unlock path.

Where to get the Atropian Blade

You start with the bare-fist melee. The Atropian Blade is a permanent upgrade that hits 4x harder, breaks yellow seal doors, and stays with you across all runs once unlocked.

Where it is

  1. Biome 1 — Overgrown Ruins.
  2. Look for a distinct large room with a yellow-marked floor in the early section. The blade is suspended in the center.
  3. Walk up to it. Press triangle.
  4. Unlocked permanently. All future runs start with it equipped.

Why it matters

  • Melee one-shots most basic enemies in biomes 1-3.
  • Unlocks yellow-sealed doors — these contain artifacts, parasites, and the biome 1 sun fragment.
  • Combos with Adrenaline — at level 3+, melee deals huge bonus damage.

Common mistake

  • The blade is not hidden. Players walk past the room because they don't expect a permanent unlock in biome 1. Specifically, look in the early section, before the boss area.

If stuck: if you've played 3+ runs and don't have the blade, you're missing it. Map the early biome 1 carefully — the room is unmissable once you see it.
