Play as Agent 4 from Perfect Dark
Have a saved game file from Perfect Dark on your hard drive. Then, create a saved game file from Crackdown 2 on your hard drive. Play Perfect Dark from Xbox Live Arcade again, and it will detect the Crackdown 2 saved game file. Agent 4 will now be playable in the Combat Simulator multiplayer modes.

Quacker Grenades
To get the Quacker grenades you first have to have a Facebook account that has been logged into from your Xbox 360 before. Using this Facebook account on a computer, you have to play the "Chuck's Ducks 2" minigame and save 20 ducks by earning them in puzzle mode and then saving them from hunters in the second part of the minigame. Once the Facebook minigame tells you that you have ducks waiting for you in the game, start up Crackdown 2 on your Xbox 360. Spawn near the Carnival in Green Bay South and then exchange the grenade you're carrying for a Quacker grenade at the Chuck's Ducks 2 booth in the middle of the carnival (it has a turret on top of it). Take that grenade back to any drop zone and you'll now be able to choose the Quacker grenades whenever you spawn.
