Here in OpenATBP, the only currency you need is Coins - earn them by playing and spend them on awesome cosmetic upgrades for your favorite champions.
You can earn Coins just by playing the game! Here's how it works:
Ranked matches can be entered via the 3vs3 Quick Match button or by using the Invite Friends option to team up.
No matter how the match ends, you're always earning progress!
Currently, Coins can be used to unlock Champion Skins - visual upgrades that let you show off your favorite champions in style. Skins don't affect gameplay, but they do let you flex on the battlefield.
Each champion has their own collection of skins, which you can browse below.
