Rocket League adding free Wasteland arena and new DLC
Players will get to play out matches in the new Wasteland arena, though that arena will be freely available even if you don't buy the DLC.
If you do invest in Chaos Run, you'll be able to race around in two new post-apocalyptic vehicles (Ripper and Grog), equip two new trails (Sandstorm and Nuts & Bolts), choose from a variety of new decals, spruce up their ride with a new paint job (Camo or Sun-damaged), equip two new wheels, or choose from a variety of new toppers and antennas.
