We make games because we love them, and because games have the power to bring people together. We established Phoenix Labs in 2014 to create a place where diverse teams of people could come together to build deep multiplayer games. Weve assembled an experienced, passionate team of developers across our locations in Vancouver, BC, Montréal, QC, and San Mateo, CA. In May 2019, we launched our first game, Dauntless. It was the first game ever to launch with true crossplay and cross-progression. Since then, we’ve watched our community grow to more than 25 million players across four platforms. Our next game, Fae Farm, will launch in late 2023. Fae Farm is a magic-infused farm sim where players create their own cozy home in the enchanted world of Azoria, available on the Nintendo Switch.
