Killzone 3 Retro Map Pack detailed

Sony's detailed the Retro Map Pack for Killzone 3, which was first announced last year.

The map pack will only be available to those who pre-order the game with either the normal or Helgast Editions, and will feature two maps that were previously in Killzone 2: Salamun Market and the popular Blood Gracht.

Salamun Market, one of the largest maps in Killzone 2, will be used for the 24-player strong Warzone mode.

"One of the largest maps from Killzone 2, Salamun Market has been re-balanced for maximum Killzone 3 carnage," said Guerrilla producer Aryeh Loeb.

"After the Helghast ambush an ISA convoy on its main road, the whole market becomes a Warzone. Nostalgia meets brand-new Exoskeleton combat on this classic multiplayer map."

Blood Gracht, meanwhile, will be used for the new single-player-like mode Guerrilla Warfare, which will house 16 players.

"Months after the nuclear blast that ruined most of the city, Blood Gracht is slowly being reclaimed by Helghan’s strange plant life," Loeb added.

"But when Guerrilla Warfare breaks out between ISA and Helghast troops, the canals once again run red with blood. The fan-favorite multiplayer map from Killzone 2 makes a triumphant return."

Killzone 3 releases on February 22 in the US and February 25 in the UK for PS3. The multiplayer beta will go live in Europe in the next hour or so, with a delayed launch in the US happening tonight GMT.
