How AI is used
Generative AI was used during development to help create some visual assets included in the game, including artwork and models, and to assist with translation of in-game text. Generative AI was also used to create promotional artwork and help write the descriptions on this Steam store page. These materials and translations are prepared in advance. The game does not use AI to generate content or code during gameplay and does not connect to external AI services.

About Fishball Defence
Build their home. Be their hero.
A round little crew. A tiny base worth defending.
Fishball Defence is a single-player roguelite base-defense game that combines settlement management with hands-on combat. As a spirit, organize your fishball crew—or possess one of them and face the attackers yourself.
When the line breaks, jump in.
Switch between your spirit and a fishball fighter. Wield weapons, dodge danger, and look for an opening to strike back. Your own actions can become part of the defense.
Get your little base working.
Place buildings on a hexagonal map and organize production, hauling, and equipment crafting. Welcome new fishball companions from the hot spring while your guards protect the workers. Prepare your economy for the next wave.
Small heroes. Everyday equipment.
Arm your crew with playful equipment inspired by toothpicks, bottle caps, and other everyday objects. Teach your companions skills and find a fighting style that suits you.
Hold this wave. Prepare for the next.
Face enemies and bosses as the waves advance. Adjust your defenses and assignments, rebuild each run, and discover your own balance between managing the base and fighting on the front line.
- Single-player base management, wave defense, and direct combat.
- Spirit possession: move between managing the crew and joining the fight.
- Visible production and hauling carried out by your fishball companions.
- Everyday-object equipment and skill learning for your crew.
- A cute miniature world viewed from a fixed isometric perspective.
