Building ALIS, an Unreal Engine 5 survival prototype set in one reconstructed post-apocalyptic real-world city location. The public source and Windows release, with documented component licenses and GPG-signed checksums, are on GitHub: https://github.com/fallintodusk/alis. Lately: tuning the metabolism system -- vitals run on real medical timelines (dehydration kills in days, starvation in weeks, compressed for play), ending in a dying state you can't just power through.
