Rare has announced that Perfect Dark XBLA will be hopping aboard the Crackdown train with a new playable character. Agent 4 will be available for free to anybody who has a Crackdown 2 save file on their 360's hard-drive. Pefect Dark detects the file and makes Agent 4 available for multiplayer combat. Neat.
It's hardly a Halo 3 beta, but it at least gives Crackdown 2 a unique little bonus. The game's actually out next Tuesday, if you can believe it, and Destructoid will have its review up on Monday. Oh and trust us... you'll want to read the review.
