This is one of those trophies that unfortunately there are no tricks that I can offer to help you. You simply have to play the game as all the unlocks are pretty much random, but I can at least offer a checklist of what you’re going to need in order to get the trophy.
Rocket League – Stocked
Collect all items – Gold
TIP: There are 194 items to collect in the game and to collect all of them you’re going to have to play at least 194 games. Win or lose, you’ll unlock a different item each time you play so you don’t need to worry about always winning in order to unlock an item. Here are the 194 different items that you’ll need to collect:
Body – 11
Decal (Every car but Sweet Tooth has 7 decals to unlock) – 70
Wheels – 25
Rocket Trail – 36
Topper – 18
Antenna – 34
Have anything additional to add to my tip? Let me know in the comments section below and I’ll add it in and give you credit. Need help with a specific trophy? I’m always looking for my next weeks tip so throw out some suggestions in the comments section. If I have the trophy I’ll post a tip on how to get it.
