While the mainline Dragon Quest games are single-player JRPGs, the series has numerous spinoffs that mix up the genre and sometimes incorporate multiplayer. Such is the case with Dragon Quest Smash/Grow, a mobile game that just launched on Android and iOS today. Smash/Grow features Vampire Survivors-style combat along with plenty of RPG-style quests and equipment, not to mention 4-player online co-op missions.
