Majesco Entertainment today announced that Mega Brain Boost, a three-games-in-one developed by Interchannel-Holon, has shipped to retail, for Nintendo DS. Mega Brain Boost includes Brain Boost Beta Wave and Brain Boost Gamma Wave, plus a never-before-released third game that includes additional drills designed to improve speed, accuracy and memory. Each game type offers four difficulty levels with 20 multiple choice problems in each. Upon completing a game series, players will receive overall scores for right brain development so they can track their progress. The game automatically adapts the difficulty to a player's skill level and includes a multiplayer option that lets friends compete head-to-head to determine who is the bigger brainiac.
