Fans of the original PC hit Boulder Dash can celebrate because developer Kalypso is creating an all new entry of the series for XBLA and PC entitled Boulder Dash XL.  The recently released trailer showcases the game’s puzzle mechanic and colorful visuals.  Kalypso describes the title as featuring “new HD visuals, a new scoring system, leaderboard support, and multiple game modes.”  Expect 25 “retro” caves to visit when the game releases sometime this summer.
