According to the reports we’ve received today, the system link for Xbox 360 version of Red Dead Redemption is currently not functioning properly.
It seems that the gamers attempting to use the game’s System Link for local multiplayer are having a hard time connecting with one another. There is no report as of now about the LAN not working properly on the PlayStation 3 version. We’re researching on this matter right now!
