A solo indie developer from Japan has upgraded the local LLM in their commercial game Hex Judge from Gemma 2 9B to Gemma 4 E4B. The medieval witch trial investigation game uses AI-generated dialogue for player interactions.

  • Conversation startup time on an RTX 2060 dropped from around 45 seconds to less than 1 second.
  • NPC conversations are smoother with improved multilingual dialogue quality.
  • The LLM runs locally on the player’s PC without requiring an internet connection or external API.
  • Hex Judge currently supports 12 languages.

This change enables faster AI interaction and allows the game to function entirely offline, demonstrating Gemma 4 E4B's capability for local AI in commercial games.
