The world ends. Something remains. A short, first-person psychological horror game about the apocalypse and unsettling divine themes, built in Unreal Engine and available free on itch.io.
We use Claude Code in our development workflow for C++ gameplay, Unreal Engine editor automation and release testing. The Flawed Architect is a released game built with this workflow.
For upcoming games, we plan to prototype Claude API-powered NPC conversations and dialogue localization. The prototype will keep responses within authored character and story boundaries, with server-side calls and usage limits.
