Phantasy Star Portable 2

 is an action RPG developed by Alfa System and published by Sega on December 3, 2009 in Japan and in September, 2010 in North America and Europe for the Sony PSP. The game featured downloadable missions and items, that were intended for the Japanese release only. A workaround allows to install the extra missions to other releases (see here). The missions were released through the game's official website and each DLC had to be copied to the console's memory stick, while weapons and outfits were released on the PSP's Playstation Store.
