Heroes of Newerth (Hon) Is a multiplayer online battle arena (Moba) Just like League of legends. Just recently it has gone free to play.
Hon has over 70 "heroes" to play as. Hundreds of items to choose from, as well as many special perks around the maps.
I personally am a League player, So I'll be trying Hon out and giving you guys an impression of how it stacks up against Lol. It looks fun, and its one of my favorite times of game to play. Game on!
