It's hardly been a month since Killzone 2's release, and Guerrilla Games is already hard at work developing DLC for online play. Just recently, GG announced the Steel and Titanium map pack, which will containt 2 new maps for KZ2: Vekta Cruiser and Wasteland Bullet.
The first takes place on, well, the Vektan cruiser. It looks like it will have a number of vantage points for sniping lower decks, as well plenty of space for firefights. It should be noted that the map is based on the cruiser after it has been attacked by the Helghast, not the shiny new one at the start of the game.
Wasteland Bullet is situated on the Helghast train seen towards the end of the campaign. This one is going to be a deathtrap, with plenty of environmental hazards to keep you on your toes. Quick reflexes will be a must!
No price has been announced for the pack yet, but we have these new video previews of the maps, courtesy of Gametrailers: [Vektan Cruiser] [Wasteland Bullet]
