Well, it was really only a matter of time until Hot Wheels came to Rocket League, right? Today Psyonix announced the DLC would release this month and include two vehicles.
The Bone Shaker and Twin Mill III will be the two cars included and cost $1.99 each. Each DLC car will be sold separately for USD $1.99 (or regional equivalent) and come with six Decals and an exclusive set of Wheels. The update will also add FREE Hot Wheels content for all players including a “Hot Wheels” Antenna and Topper, “Treasure Hunt” Flag, and “Shark Bit” Topper.
