Where to find Game Builds for Sound Design Practice, Etc.

Anyone know where someone might find downloadable builds of quality, comprehensive game environments created with Unreal Engine for Sound Designers to practice with and / or create demos from? Comprehensive scenes with props, characters, and such, ready to build out with sound? the FMOD tutorials I’ve worked on are helpful, but they’re pretty sparse in terms of activity, and wouldn’t make for much of an exciting demo. Don’t mind paying for it. Any thoughts?

There are a variety of UE4 Sample Projects in the Learning area of your Epic Games Launcher and there are a lot of assets, environments, and scripts available at the Marketplace (including free ones from Epic Games e.g. Paragon models and environments).
