official website, and we can't imagine anyone will be prepared for the barrage of options listed when you click that link. No less than eight different pre-order bonuses, split between ten different US and UK retailers have been dreamed up by marketing. In typical Rockstar fashion, the practice of "exclusive" bonus content has become excessive bonus content.
Among the options listed are the "Golden Guns Weapon Pack" (more "Fame" per kill), from Amazon, which also comes with a $10 Amazon gift card; the "War Horse," a steed that Rockstar claims can't be bested by any other horse in the game, only available from Best Buy and HMV; and the "Deadly Assassin Outfit" from UK retailer Game (and maybe GameStop, if the getup wins the vote -- uh-huh, there's a pre-order vote). So yeah, we're going with the Amazon option, too.
