Rocket League may not have an official map editor just yet, but it looks like modders are taking the matter into their own hands.
New Rocket League leaks suggest that there'll be a Mortal Kombat crossover in this game soon, which could have Motor Kombat karts in it.
The Rocket League 2.46 patch notes include Online Free Play, a brand new arena, Neo Tokyo (Arcade), and adjusted centre of mass on a few cars.
Rocket League season 17 arrives in December, along with new Online Free Play, Split Shot modes and a new Rocket Pass.
