ABOUT THE SERVER / ANUNNA-KI: KATABASIS
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
Venture into the wilderness, face its creatures, and meet rival players with steel and spells.
Two rival cities, Babylon and Uruk, stand against one another under the eyes of Marduk and Inanna. Your journey begins in a divided world.
Take up weapons or wield magic. Fight monsters beyond town, where other players bring a different kind of challenge.
Weapons and armour change how your character looks.
EQUIPMENT / FIND YOUR NEXT GOAL
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 / 19 OCTOBER 2026
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.
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.
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.
