Sources have revealed that 2K Games is working on a new game called "Gravity Goal" that is aiming to compete against Rocket League. The project, which is currently called Gravity Goal allows players to drive TRON-like bikes rather than cars.
The goal of the game seems to be just like Rocket League, where matches consist of 1v1, 2v2, or 3v3. Players need to score by hitting a ball with their vehicles into the back of a goal by using their vehicles. One slight difference with how Gravity Goal works compared to Rocket League though is with the addition of 'discs' that players can use to throw at the opposing team's vehicles to cause damage.
Tom Henderson does have a good track record when it comes to leaks, but still better take it as a Rumor.
