Cross-platform play is getting some fresh company with the new additions coming to the soccer-meets-vehicular-mayhem of Rocket League. As part of the game's next update, the developers at Psyonix say they're adding "rare" and "very rare" items (hats, paintjobs, etc..) that will augment a particular skill of yours. More than that, if you build up a collection of gear that you'd rather not use any more, have countless duplicates of or have found more powerful/uncommon versions of, soon you'll be able to trade items in for more prestigious implements.
