buying a key to open a Crate. Credits are the "new exceptional money" coming to Rocket League with the December update. They can be utilized to make Blueprint things, purchase stuff from the Rocket League Items new Item Shop, and move up to Rocket Pass Premium.
"Like the Crate things that went before them, Blueprints can drop with unique ascribes like Painted, Certified, and Special Editions," Psyonix wrote in a blog entry sketching out the system.The thought is that players will recognize what they're getting from Blueprints rather than "shock mechanics" of plunder boxes, which have been dubious. In May, United States representative Josh Hawley proposed new enactment that would boycott pay-to-win mechanics and disallow organizations from selling plunder boxes to kids. Psyonix's change to Blueprints is one approach to deal with the debate. Adding a plunder box "X-beam scanner" to Counter-Strike: Global Offensive in for French players is another way.
Anyway, in Rocket League, Crates will stay until the December update, and when it does, Rocket League keys will be changed over into Credits. Cases, as well, will be changed over into lolga Blueprints "of a similar arrangement," Pysonix said.
