During one of our research weeks, our team explored the capabilities of iOS's mixed reality multiplayer system and ML-powered skeletal tracking. In just five days, we developed a game for up to six players. Two competing teams race to collect cards scattered in real space, but there's a twist: players must look through portals to determine if a card matches their team, deals damage, or is a trap. To collect a card, players must touch it with their phone—but watch out, you're not the only one hunting for it!
