SideQuest is a Unity-based, free-to-play browser-based RPG. Wait! Don’t go! It gets better!
In certain respects, SideQuest is a robust MMO: players can fight each other (synchronously or asynchronously) in arenas and battlegrounds, join forces to go on raids or quests, form guilds and trade loot, compete on a leader board, and go head-to-head in a full-featured collectible card game.
