20 Things You Didn't Know About Rocket League
18. It Wouldn't Exist Without Unreal Tournament 2004
Rocket League actually wouldn't exist at all without the help of the Unreal Tournament franchise, specifically Unreal Tournament 2004.
Shortly after he founded Psyonix back in 2000, Dave Hagewood was hired by Epic Games to work on Unreal Tournament 2004, helping develop the vehicle-centric Onslaught Mode.
Hagewood took the knowledge of the Unreal Engine he acquired working on that game and started toying around with his own vehicle-centric project, eventually adding in a ball.
This effectively became the prototype for Supersonic Acrobatic Rocket-Powered Battle-Cars, which Hagewood would spend the next few years working on. The rest, as they say, is history.
