Lost Heroes, Namco Bandai’s Gundam + Kamen Rider + Ultra Man crossover dungeon-crawler, was last week’s best-selling new release.

Namco Bandai’s dungeon crawler starring Gundams and Kamen Riders is out this week.

Lost Heroes brings together characters from the Gundam, Kamen Rider, and Ultraman universes. How many characters? Over 300, but only fifteen like Wing Gundam, Kamen Rider W, and Ultraman Mebius are playable.

That mobile suit sure likes to show off.

Usually, first person dungeon crawlers are played completely through the heroes’ eyes. But, the licenses for Kamen Rider, Gundam, and Ultraman are just too lucrative to have all of these characters in the back row.

Gundams, Kamen Riders And Ultramen team up for a good, old-fashioned dungeon crawl in Lost Heroes.

Famitsu confirmed three more heroes for the game: Kamen Rider Den-O, Z Gundam, and Ultraman Taro are in the game.

Originally announced as a Nintendo 3DS exclusive, Lost Heroes is coming out for PSP too.

Namco Bandai keeps bringing Ultraman, Gundam, and Kamen Rider together, but in Lost Heroes you won’t be punching your way through enemies. This Nintendo 3DS game is a dungeon crawler.

… for a dungeon RPG! Screenshots of Kamen Rider Den-0, Kamen Rider #1, Nu Gundam, and Ultraman Mebius inside.

No, this isn’t another Super Robot Taisen spinoff. Lost Heroes is entirely different, especially because it’s a dungeon RPG.
