The new ground reset move seems to use the "ceiling fall" mechanic to preserve a jump indefinitely without having to touch the ceiling. This new mechanic can be initiated from the ground or wall and will preserve a flip as if the player had fallen from the ceiling. By jumping and then boost-jumping between when their front and back wheels hit the ground, the player skips back up into the air and can flip at will.
Psyonix has rolled out a major "Progression Update" for Rocket League Trading that completely revamps the game's progression system (hence the title) and eliminates the level cap. The update also adds a new "Clubs System," new achievements and trophies, and makes numerous "quality of life" improvements as well.
The update, teased in June, changes how experience is awarded—it can now only be earned in Online Casual and Competitive Matches, and will be based primarily on match length rather than score—and how levels are gained. Instead of it "taking progressively longer to earn" levels past 20, successive levels will require a flat amount of XP, and the cap at level 75 is gone as well, so you can climb as high as you want. Existing levels will be converted to www.lolga.com the new system based on factors including the total number of online matches played and total XP earned. Players at or below level 40 should end up with roughly the same level they had previously, while those above 40 will end up at a higher level. Players who have already hit the level cap will be granted extra levels based on the number of online matches they've played.
