6 DEVS Make "SCHEDULE I" without COMMUNICATING!

Six independent game developers each take turns building a clone of the indie hit Schedule I using Unreal Engine, without communicating with each other. Each developer adds their own systems and assets: player movement and inventory, a phone UI with apps, NPC quest and dialogue systems, an RV and ATM with driving mechanics, a cyberpunk urban environment with additional product variants, and final polish including UI improvements, visual effects, and a low-poly car model. The result is a surprisingly cohesive game loop despite zero coordination between contributors.
