The downloadable content is also available as a pre-order bonus from participating retailers. The map pack includes two popular multiplayer layouts from Killzone 2, including one of our favourites: Salamun Market. The other map is Blood Gracht.
Guerrilla promises you'll get to see a video comparison of the maps in a couple of days. For now you'll have to make do with screenshots.
There's more information after the jump.
