MMO Grinder: Heva Clonia review, It’s a beat-em-up! It’s a World MMO! It’s… really really easy. Another cute-style MMO gets released stateside with the addition of OGPlanet’s Heva Clonia, a grind-centric action MMO with an interesting “cloning” system that allows you to convert enemies into allies. Does this mesh of genres mix well enough?
