Home Sweet Home : Online is an online action game set in Niwarn, a limbo between the human and spirit worlds. In Survive Mode, one Warden hunts four Visitors, who cooperate to complete an objective while using distinct character abilities. Once it is complete, they face a choice: work together against the Warden or leave the arena.
Battle Mode pits two teams of four against each other. Visitors perform an awakening ritual to obtain a Warden Soul; its holder can become a Warden and hunt the opposing team, while the team collecting the most souls before time runs out wins.
