Rockstar has released a new update for Red Dead Redemption, fixing a few nagging issues that users were experiencing.
Most of the fixes tackle the issues that people were having when playing online, therefore any Nat issues or connection problems you were having when playing the game should now be resolved.
In addition, this update includes support for a new playlist by popular demand: Hardcore Free Roam, supporting only expert aim. The new playlist will be released once this title update has time to propagate on both consoles. Rockstar says it will update users once this is live.
