MIR4 is an open-world fantasy MMORPG where you explore the world of MIR, follow quests, and develop a character from one of four classes: Warrior, Sorcerer, Taoist, or Lancer.
Hunt monsters and bosses, collect resources through gathering and mining, and craft items as you progress. Automated movement and combat handle many routine tasks, while direct encounters can involve dodging and using skills.
Join a clan for group raids and large-scale PvP. Clans can fight to control the Hidden Valley and its taxes or contest castle sieges; special chest loot can also be claimed by players beyond the group that defeated a monster. The game supports play across PC and mobile.
In the supplied reviews, players who enjoy MIR4 often cite its visual world, character progression, and variety of activities, from gathering and boss fights to clan wars. Some also value playing with friends across platforms or leaving routine farming to automation. Other reviews find the progression repetitive or too time-consuming, and describe competitive play as costly.
