Mettle is an 8-bit step counter RPG for iOS. Your real-world steps are the damage your party deals to a shared weekly monster — walk together to win, earn coins, and grow a roster of heroes. Join a party with friends or family. Each week the party takes on an encounter — a monster whose total HP scales with how many of you there are. Everyone deploys one hero and walks: your steps from Apple Health become damage, multiplied by your hero's rarity. Drain the monster's HP before the week ends to slay it and claim coins. Spend coins in the shop to unlock stronger heroes.
