A new map pack titled "Steel & Titanium" will be available by the end of April and includes two new maps: the ISA tech cruiser provides for a very vertical map whereas the train-level makes a reappearance in the form of, what looks to be, one of the best multiplayer maps we've played for a while.

Seriously, the train-level was one of our absolute favourite levels on Killzone 2, so we can't wait to play it.

Alongside the DLC announcement, Guerilla's Hermen Hulst announced that the second DLC map pack would have "retro" somewhere in the title. Expect some maps from the original Killzone brought to life.
