This is the UnrealTournament 04 first person shooter game introduced in 2017.
A new beginning of the end I would say , the game lacks on development, it relies on development from users taking lot’s of time and effort in the game.
It is downloadable with the Epic games launcher , the same wich you can download Fortnite etc.
You can also download Unreal Engine with lots of possibilities on developing and also Unrealed the UnrealEditor to create Game Levels.
