How to play a uproject

so im a unreal engine noob and i got a project from a news article but i cant get it to run/play like a game when i launch the uproject file with the engine, it just shows a black screen and the editor just shows a flat square area with no textures. here is the link to the project.
warning!! its 1.5gb so it may take a little bit to download if you choose to.

i hope someone can help :slight_smile:
