Here's word: "Three Kingdoms Brawler, a free-to-play action brawler, is an updated version of the classic side-scrolling arcade beat-em up games for the new generation of online gamers. Set to officially launch this summer, players can now participate in the pre-launch beta by visiting http://tkb.the9hub.com.
