Bad news for people hoping to play the 2 player co-op mode in Street Fighter X Tekken with an in-person friend against others online on the Xbox 360, as Capcom USA vice president, Christian Svensson, recently explained the situation.
Will 2 player local co-op on Xbox Live be patched in for the 360 version of Street Fighter X Tekken? — Weegee
Svensson: It will not be patched and apologies for the manual inclusion. Seems it was an oversight. The difference has to do with how Xbox Live 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 Xboxes)."
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.
Utter bullshit answer from Capcom. but you should know before buying it. that its not in the game well not the 360 version.
