MLB Dugout Heroes announces this subscription-free sports MMOG will go live on April 27, though the open beta will continue to run between now and then if you want to check it out right now. Here's the party line on the game and how it works: "MLB Dugout Heroes is the first fully licensed and online-based PC baseball game in North America, featuring all Major League Baseball players and stadiums from the past and present. In addition to the MLB-licensed game features, MLB Dugout Heroes has many unique gameplay attractions including its unique and realistic leveling system which allows players to grow stronger and better as they continue through the game. In addition, special points are given to players as they complete baseball missions (quests) given daily or weekly, and these points can be used to purchase new players, uniforms, items, and more."
