Move over Smash Bros., Namco-Bandai's upcoming Strategy-RPG, Project X Zone, is a crossover of epic proportions. The game combines characters from Namco's Tekken universe, Sega's Valkyria Chronicles series, Capcom's Street Fighter franchise, and more.

This upcoming 3DS title includes more than 50 characters from 29 franchises. Players use pairs of characters to navigate the world, enlisting the help of another character for battle assists. Namco says the game includes solo and support attacks, cross hits, and finishing moves. In the story, a time rift opens up, which offers a somewhat tenuous explanation as to why characters from such a wide variety of games and eras are able to stand next to one another. Highlighted franchises include Mega Man X, Darkstalkers, Tekken, Shining Force EXA, and many others.

To celebrate the game's release, Project X Zone will include a mini-art book and poster featuring the characters and famous gaming franchises represented in the game as well as a music CD soundtrack.
