Chances are you didn't reserve and purchase Red Dead Redemption at several different retail locations when it launched last year, because that is something a crazy person would do. If you're missing out on the bonus in-game items offered as pre-order incentives, Rockstar's offering you a chance to complete your collection next week. The Assassin Outfit (which doubles Dead Eye regeneration), Golden Guns Weapon Pack (which increases Fame earned) and War Horse (which is a war horse) are coming to XBLA and PSN next week for 80 Microsoft Points ($.99) a piece.
Rockstar apologized on its blog for the time it took to bring these items to market, citing "unanticipated technical delays" as the cause of the hold-up. It seems they've got the kinks worked out -- the same blog post promises LA Noire's pre-order bonuses "should become available as DLC much, much sooner."
