If you want the full Uncharted 3: Drake's Deception experience, you need to be locked and loaded for all future content.
After the fans said they'd like an option to grab downloadable content at a discount, SCEA has responded with a what they're calling the Uncharted 3 Fortune Hunters' Club .
Members are entitled to the first four multiplayer map packs and the first three multiplayer skin packs for Naughty Dog's highly anticipated gem. This DLC will be available in November and if you pre-order now, you can grab it all for only $24.99; doing so will also net you the exclusive Fortune Hunters' Club Theme. When each new pack hits the PlayStation Store, you will receive an XMB message that links you directly to the content. Then, just download and go. The total value of all the packs combined is over $45, so that's basically a 45% savings on 7 multiplayer packs, plus the free theme.
Perhaps we should have similar deals and "clubs" for other games, especially those that rely heavily on multiplayer (more so than Uncharted ). If you're hooked on a certain game, it'll undoubtedly be more attractive to pre-pay for all the DLC you know you're gonna pay for anyway, and at a hefty discount, too.
