Reports have surfaced revealing that the Xbox 360 version of Street Fighter X Tekken cannot be played online in Tag-Team mode with two players on the same system. The PlayStation 3 version does not have this shortcoming.
Recently, a user on Capcom’s forums asked if the issue would be patched at a later date. The answer to that is “no,” and Capcom’s Christian Svensson addressed the issue in a reply on the forums:
“It will not planned to be patched and apologies for the manual inclusion. Seems it was an oversight. The difference has to do with how XBL differs from how it handles online and offline accounts.
According to the team:
‘PS3 version: It is possible to mix and match online and offline players for scramble battles and pair play battles. Two local players can play on the same PS3 using 1 PSN ID, and play against other players online.
360 version: It is NOT possible to mix and match online and offline players for scramble battles and pair play battles. So you either have to have all players be offline and local (so 4 players, 1 xbox) or have all the players be online (4 players, 4 xboxs).’
The reason for this difference is because of the architecture differences between gamertags and PSN IDs. I’m not sure of the technical details, but basically it amounts to: Sony made it so you can mix and match online and offline, and Microsoft made it so you can’t.
EDIT: BTW, I’m still digging into this explanation. I’m also confused by it.”
We’ll provide further updates as Capcom share more about the situation.
