Guest account feature avalible?

Sooo, a lot of people have been saying it exists yet I cant seem to find or figure it out…

Is it possible to play as a Guest account in Online battle?
I have tried pressing start during the character select screen and everything else

Any help? I’m still in the dark as to weather this game even has this feature or not

Any feedback appreciated, thanks.

Currently it appears not to be working on the xbox 360 version, only the ps3 version. In the ps3 manual it gives direction on how to have partner play, but the text is missing in the xbox 360 manual. People are hoping it will be patched, but many people are doubtful because it is not existent in the 360 manual and because the PS3 has many exclusives.
