With the release date of Killzone 2 coming ever closer, word of a demo for the highly anticipated shooter has come out. However, if you want in on the action, you’ll need to pre-order the game, it seems.

Games retailer GameStop is offering “exclusive access” to the downloadable demo in exchange for a $5 pre-order, reports Joystiq. Those that reserve the game in-store will receive a card with a download code. Online customers will get the code emailed to them on February 3, suggesting that the demo will be released on that day.

Sony is yet to comment on the demo’s release date. Killzone 2 is due out exclusively on the PS3 on February 27.
