PromptStrike is a browser based 3D voxel arena combat game powered by Gemini at every layer. Describe a weapon like “black hole cannon” and it generates executable JS in seconds. An Arena God AI studies your tactics, taunts you, and mutates the arena to counter you. Enemies evolve identities and resistances based on your playstyle, while difficulty adapts in real time from player telemetry. On death, Gemini writes a unique 300 word War Chronicle of your run, orchestrated by 6 LlamaIndex agents returning structured JSON instantly rendered in game.
