Namco Bandai published a trailer of the upcoming crossover RPG Heroes Phantasia, that will feature many characters from a lot of popular anime series like Slayers Revolution, Sergeant Frog (Keroro Gunsou), Darker Than Black, Blood+ and more.
The game will be released on PSP in Japan on January the 19th, and will probably never see the light of day in the west due to the licensing issues involved in Anime crossover games. It’s a tactical turn-based RPG somewhat similar to the Super Robot Wars series.
You can check the trailer past the cut. If you love anime, you’ll probably love it.
