Play as Agent 4 in Rare's XBLA title. Rare's announced that hidden away in its Xbox LIVE Arcade shooter Perfect Dark is a playable character known as Agent 4 - a new character skin based on the imminent Crackdown 2. This black-suited gun fanatic will be unlocked for use in multiplayer once a Crackdown 2 game save is detected on the Xbox 360 system. So, if you fancy shooting people on Xbox LIVE dressed as a Crackdown Agent you'll want to pick up the open-world sequel when it hits stores on July 9.
