ABOUT THE SERVER / ANUNNA-KI: KATABASIS

Playable now.
A world still taking shape.

Helbreath was the game that made us love this kind of PvP: quick reactions, a dangerous world and friends who look out for each other. Anunna-Ki: Katabasis brings it into Unity with a new identity built around Babylon and Uruk.

Choose your city, level your character, hunt monsters and earn equipment to take into PvP. The public beta is open, with development continuing alongside player feedback.

Come try the game and help shape the remaster.

THE WORLD / STILL BEING REMASTERED

Beyond the city walls.

Venture into the wilderness, face its creatures, and meet rival players with steel and spells.

I

Choose your side.

Two rival cities, Babylon and Uruk, stand against one another under the eyes of Marduk and Inanna. Your journey begins in a divided world.

II

Fight your way.

Take up weapons or wield magic. Fight monsters beyond town, where other players bring a different kind of challenge.

III

Wear your story.

Weapons and armour change how your character looks.

EQUIPMENT / FIND YOUR NEXT GOAL

Explore the gear.
Plan the hunt.

Browse the complete item catalogue, compare base stats and find possible monster drops. Then pick a map and plan your next hunt. Equipment artwork is still being refined for the remaster.

DEVELOPMENT NEWS / 29 OCTOBER 2026

Patch 1.0.158 is live

Anunna-Ki: Katabasis title screen: Marduk and Inanna on either side of the game’s title.

Restart the launcher to update.

What we fixed today

  • The cooking window works like Manufacturing now.
    The problem: it opened straight onto Grilled Fish, so you never saw a list of what you could cook.
    Now: a recipe list on the right (anything you can cook right now is green) and six ingredient slots on the left. Nothing is picked until you choose.
  • Each recipe shows what it needs.
    Pick Grilled Fish and you see "Any fish" with how many you carry, the Cooking skill it needs next to yours, and your chance to cook it or burn it.
  • Your meal sits on the hunger bar.
    The problem: the stone for the meal you ate floated above the bar.
    Now: the bar is a little shorter and a smaller stone sits in the bar's own column. The bar takes its colour from what you ate.
  • You can read your food buff.
    The problem: hovering the meal stone showed white text on a white panel, drawn behind the other windows.
    Now: white text on a dark box, above every window.
  • The Demon Slayer has a new bag icon.
    The problem: the icon was too bright to read well.
    Now: a darker version.

Still to fix (known in this patch)

  • Stew recipes show in the cooking list but cannot be cooked until the next server update.
  • With a Blood Sword, Blood Axe or Blood Rapier equipped, your max HP shows one fifth lower than it really is. The server keeps your real HP. The display is fixed in the next server update.

Coming up

  • Voice chat.
  • Guilds.
  • The male cape.
  • Stews you can cook.
  • Brighter monsters, tuned one at a time, starting with the Icebound map.
  • More "then vs now" weapon clips.

22 October 2026 — Death Valley run, testing Axe speed

DEVELOPMENT NEWS / 22 OCTOBER 2026

Death Valley run, testing Axe speed

A quick hunt from Anunna-Ki: Katabasis, our reimagining of Helbreath. I’m working on a fuller trailer, but wanted to share some gameplay along the way.

The beta is open, and we’re looking for PC and Steam Deck testers. Come try a hunt and tell us how it plays.

DEVELOPMENT NEWS / 19 OCTOBER 2026

See the beta in action.

Watch an early garden hunt.

You can now watch a 45-second garden hunt on YouTube, showing movement, spell casting, monsters and the interface. It is actual beta gameplay recorded on 15 October 2026.

Watch the gameplay clip ↗

There is also an IndieDB project page with screenshots and information about the game. For more footage, see the gameplay gallery above.

Anunna-Ki: Katabasis is an early public beta, bringing Helbreath into Unity with a new setting around Babylon and Uruk. Maps, artwork, animations and the interface are still being remastered. Development uses AI-assisted tools, including 3D artwork baked into sprites.

15 October 2026 — The first public beta

A starting point for the remaster.

The early beta is playable: level up, hunt, earn equipment and join the conflict between Babylon and Uruk. We’re opening the doors while the world is still being remade, so players can help us find what needs attention.

Maps and visual consistency are a major focus. Equipment presentation, animations and the interface also need further work. Expect rough edges and changes as development continues.
