Monster Hunter Freedom Unite has become the first PSP game to ship over 3.5 million units, according to Capcom.
Released in Japan in March 2008, Monster Hunter became the best selling PSP game of 2008. In October, an enhanced 'Best' version of the game was released and shipped a further one million copies. The 3.5 million figure takes into account both versions of the game.
Following its popularity on PSP, Capcom will release a new Nintendo Wii instalment to the series on August 1 entitled Monster Hunter 3(tri-).
The game will be the first third-party title to be bundled with the Nintendo Wii and sold as a special pack. In addition, Capcom is planning a series of special preview events in July and 'Monster Hunter Festa '09' in August, where fans will take part in Monster Hunter themed celebrations.
