Two more games are being added to the Xbox Game Pass library this week, the first of which is out now. Psyonix's hit soccer-with-cars game Rocket League is now available in the subscription service catalog, while Warhammer: Vermintide 2 is coming on July 11. [Update: Vermintide 2 is also out now.]

To celebrate the Game Pass launch, Psyonix is offering discounts on some Rocket League DLC. For example, Rocket League's Fast & Furious '70 Dodge Charger R/T is on sale, while the Batman v Superman: Dawn of Justice Batmobile and the DeLorean time machine from Back to the Future are also marked down to $1.80 instead of $2.
