"Nearly a year in the making, League of Legends: Dominion represents the largest and most ambitious update to League of Legends since its launch in October of 2009," Riot stated in its release announcement. "League of Legends: Dominion is the latest example of our ongoing commitment to bringing you the best of the MOBA genre in new and innovative ways."
Dominion tweaks the Multiplayer Online Battle Arena genre of "attack a base" by shifting the action to several capture points. Those who've played Battlefield's Conquest mode or most any other game's "king of the hill" will catch on quickly. %Gallery-129944%
