Joseph Writes- Eden Rising is a neat hybrid of genres. It features online co-op, in addition to single player, and this is where the game shines the brightest. However, this is one of few times Im going to come out of the gate telling you not to take my word for it. Eden Rising features a free to play version and in it, you can play through and explore three of the areas of the game. But if you play on a server whose host owns the full version, you can access those features.
