Marvel Ultimate Alliance 3: The Black Order has been updated to Version 1.0.2, and it seems the sole purpose of this mode was to remove a recently-discovered glitch. The glitch let people fill out their party with duplicate superheroes, meaning you could have 4 of the same Spider-Man on your team. Version 1.0.2 yanks that glitch, and anyone who wants to play online will have to use Version 1.0.2 as well.
