Sony has confirmed that the first batch of Killzone 2 DLC, a set of two maps dubbed Steel and Titanium, will hit the PlayStation Network on April 30. While the price still remains an unknown quantity at this point, both maps are said to come packed with “new gameplay elements and strategic twists.”

In Wasteland Bullet, the action takes place on a fast-moving bullet train that cargoes goods from Pyrrhus and the Wasteland. With obstacles looming overhead, which can induce damage if not careful, players will need to stay aware of their surroundings when facing off against the enemy. The second map is Vekta Cruiser, which is set inside a Helghast-infested tanker ship.

Like we said, still no price. Wouldn’t expect it to cost more than $5, though. Might be free if Sony is feeling generous.
