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!
We can confirm right now that it’s not working as we’ve tested it. We have reached Rockstar Games if there will be a fix to this problem. We will update this post once we hear something about it.
UPDATE: A title update is now live that will fix this issue.
