Guerilla Games announced day-of-release DLC for Killzone 3 with the Retro Map Pack, containing two classic Killzone 2 multiplayer maps.

Salamun Market and Blood Gracht have been updated for Killzone 3 multiplayer madness, available for download Feb. 22 with the release of the full game.

This is the same map pack that comes free with pre-orders of the Helghast Edition.
But never mind that–the Killzone 3 multiplayer beta is live right now!
How does release-day DLC suit your Killzone needs?
