Realm of the Mad God
Realm of the Mad God is a cooperative MMO shooter. Play together with thousands of others in a frantic real-time bullet hell game. Dodge blasts from devious monsters while you work with friendly teammates to take down the Mad God himself. Realm is a major advance for MMOs, putting dozens of players into the middle of an intense action game straight out of the arcades.
