15.09.26 - UPDATE - WEAPON ADAPTATION SYSTEM

O3: Hollow Descent Playtest · published 15 Sep 2026, 18:44 UTC

All newsPlayers around this dateRead on Steam

A new progression system has been introduced into the O3 Demo 2 build: Weapon Adaptation.

Weapons will continue to spawn randomly throughout the dungeon exactly as before, but every weapon now has its own persistent progression happening behind the scenes.

HOW WEAPON ADAPTATION WORKS

Each weapon can progress through multiple Adaptation Tiers:

Base - Tier I - Tier II - Tier III / MAX

By using a weapon during your runs, defeating enemies with it, and continuing to use it over time, that weapon earns Adaptation Points.

Once enough progression has been earned, the next Adaptation Tier will automatically unlock.

Different weapon rarities have different progression requirements. Common weapons generally require more points, while rarer weapons such as Epic weapons require fewer points because they appear less frequently during runs.

WHAT HAPPENS WHEN A TIER UNLOCKS?

When a weapon reaches a new Adaptation Tier:

  • An on-screen notification will appear.
  • The new tier will be permanently unlocked.
  • The Codex will update with the new weapon stats and changes.
  • Future versions of that weapon found inside the dungeon will spawn at your highest unlocked tier.
  • The equipped weapon icon will display its current Adaptation Tier: I, II or MAX.

Adaptation upgrades can change different aspects of a weapon, including its stats, behaviour and additional effects.

There is no upgrade selection screen and no direct control over when a weapon evolves.

The idea is simple: use the weapons you find, and the weapons gradually adapt as you progress through O3.

I’d really like to hear how the system feels during normal runs - whether progression feels too fast or too slow, whether specific Adaptation Tiers feel too strong or too weak, and of course if you encounter any strange behaviour, glitches or bugs.

Thank you again for helping test the build and for all the feedback.

Happy playing, Explorers!
