Rocket League's rapid ascension from cult indie classic to mainstream monster could probably be marked by the addition of the Batmobile, but we reckon these Hot Wheels classics are arguably even cooler. Psyonix has announced that Bone Shaker and Twin Mill III are launching as DLC cars starting 21st February. They'll cost $1.99 apiece and will ship with exclusive wheels and decals.

Don't worry if you can't afford the content right now, though, because you'll be able to unlock new Hot Wheels-themed toppers, antennas, and flags for free purely by playing the game. You can get a better look at all of the new content on the game's official website, which you'll find through here.
