Rocket League Items will change how updates and rewards work one month from now when Crates are supplanted by Blueprints. Paid Crates are on out, and Blueprints will utilize another top notch money, Credits. Outlines will let you see precisely what they will manufacture, so it's in every case clear what you're getting for your cash. This will remove a portion of the arbitrariness from the plunder game in Rocket League.
Designer Psyonix has additionally itemized how Blueprints will function in another post on the official RL Items site. When the update hits, online matches will start to remunerate players with "uncovered" Blueprints. You can construct the things on these Blueprints by spending Credits, clutch them for some time, or exchange them with another player. Any current Crates that you have in your stock when this update happens will change to "concealed" Blueprints, which you would then be able to change to uncovered Blueprints at no additional expense.
