Right now, you can get your hands on Rocket League Momentum Series items through the in-game shop. These items won’t be around forever, though. In fact, they’ll only be available for 48 hours. As of 1:00 p.m. PDT on June 25, the items will disappear from the shop, and no one knows when Psyonix will bring them back.
The Rocket League Momentum Series items will cycle into the game through blueprints as well as individual items in the Item Shop. The new collection adds in more than a dozen new items, including the Peregrine TT, the Huntress Decal for Fennec, and the Interstellar Animated Decal.
However, there’s one item in particular that you’ll probably notice other players begin to use more and more. I doubt that you’ll be able to enter a match soon and avoid it. That item is the Gravity Bomb Goal Explosion. When you score a goal in Rocket League, you usually get blown away from it in a celebratory explosion. With Gravity Bomb, however, you’ll instead be sucked into that explosion. This will no doubt make for some very messy pileups after certain players score a goal.
Other items in this collection include the Hardline Decal for Fennec, Cutter Wheels, and even a Quasar Boost. My personal favorite is the HNY Wheels, which look like Psyonix ripped them right out of a beehive.
