The Alto Collection

Join Alto and friends as they set out on the adventure of a lifetime. Race down alpine slopes, over windswept dunes, through ancient woodlands and the long forgotten ruins of both critically acclaimed titles: Alto’s Adventure and Alto’s Odyssey. Along the way you’ll pull off daring backflips, grind over rooftops and leap over vast chasms as you journey to discover what mysteries lie beyond the horizon.
