Fall Guys

For this achievement, you'll need to purchase 10 different items from thein game store. Items unlocked by obtaining crowns or progressing through the season will not count, only items purchased with either Kudos or Show Bucks count.

All items within the store count for the achievement. This includes costume pieces, colors, patterns, banners and nicknames.

If you want to get this quickly, the best course of action would be to buy a couple Show Bucks, the game's premium currency. Purchase some of the costume sets which should get you a few items right off the bat.

If you don't want to purchase Show Bucks, then you'll need to obtain Kudo's for the items that can be bought with them. Each day you'll have a few daily challenges which total up to 200 Kudos. Weekly challenges and progressing through the season will also earn you a sizable amount of Kudos. Most items in the store that cost Kudos are typically 1000-2000 Kudos so you'll need to save up.

There will be a daily set of items in the store that rotate every 24 hours. There's typically a banner and nickname in this daily set that cost a combined total of 700 kudos. Purchase these two items instead of the pricy colors or patterns which cost more Kudos yet only contribute one item towards the achievement.

While the normal way of getting this achievement might be buying items from the in game store using the various currencies, I got this achievement after linking my Amazon account to my Fall Guys account.

Twitch Prime has been giving away Fall Guys outfits for a few months now (and has a few more months coming up as of this post). Claim the items through Twitch Prime, link your accounts, and you can get progress towards this achievement (or maybe enough items to complete it).

Claiming outfits through Game Pass Perks may also help towards this achievement, but I am unsure.
