Crackdown on Perfect Dark
Is playing a game as a character from a completely unrelated game your thing? Well, if you have Perfect Dark on XBLA and buy Crackdown 2 next week, you’ll be able to play as your Crackdown agent in Perfect Dark multiplayer. Seriously. We’ve been seeing a lot of this kind of synergy recently what with all the cameos you could unlock in Lost Planet 2.
So what do you have to do to unlock this? Just start a new game in Crackdown 2, then quit, then play Perfect Dark. Bam, most expensive DLC ever.
