R2 Online is a Free to Play Online Fantasy Role Playing Game (MMORPG) with a core focus on guild-based castle siege gameplay. Though the high-quality graphics and intense combat mechanics in R2 Online are undeniably impressive, it's the small innovations, such as the Team-Based PvP and Transformation System, which allows for more than 100 unique transformations, that really set it apart from the pack.
