Riot Games have made Dominion, the brand new game mode for League of Legends, available for download. The new game mode, takes a step away from the DotA inspired shenanigans of the main game and offers up a "King of the Hill" like experience, naturally with all the RPG trappings you'd expect from League of Legends.
Naturally, it's a free download so if you're into League of Legends you should go ahead and give it a try. Go on.
