ATLYSS places players in a strange world of creatures, critters, unexplored locations, and deep dungeons. Its character creator offers five playable races, with customization for color, head, and body, setting up a personalized adventurer before the journey begins. The premise leans into exploration and the mystery of a shattered world rather than a narrowly described questline.
Class advancement begins with the Novice and branches into three distinct roles. Fighters focus on melee attacks that stagger foes, Mystics use offensive and supportive arcane magic, and Bandits combine ranged weapons, traps, and quick melee strikes. Quests invite parties to hunt creatures, find new places, and uncover the world's secrets, giving combat and exploration a shared purpose.
ATLYSS can be played alone without an internet connection or with friends online. Character progression is saved locally, and the same character can move between solo play and a net-play session.
