While a bit of confusion has been swirling around the upcoming downloadable content (DLC) for Killzone 2, entitled Steel and Titanium, Sony Public Relations Manager, Alex Armour (cool name) has posted on the US PlayStation Blog to try and sort out the mess.

First and foremost, Steel and Titanium will not be a free DLC download, although the price is still to be determined. Also, in what Armour calls the “first DLC pack” (which logically means there will be a second), you’ll be getting two new multiplayer maps, Wasteland Bullet and Vekta Cruiser, explained thus:

“The first map in the pack is Wasteland Bullet, and the action will take place on the bullet train that transports goods and troops between Pyrrhus and the Wasteland. The game is a frenzied firefight to wrestle control of the train from the enemy and into the hands of your faction.

“With the train moving at full speed, players will need to remain aware of the immediate environment as well as enemies – hitting an overhead obstacle at this speed will mean instant death.”

A video below shows some great in-game action from Wasteland Bullet:

“The second map,” continues Armour, ”Vekta Cruiser, will find ISA troops boarding a vast ship with the goal to repel a force of assaulting Helghast troops while also protecting the cruiser itself from heavy Helghan fire. The action takes place entirely indoors in a frantic and claustrophobic battle where attackers lurk around every corner.”

Here’s another video from that map (Vekta Cruiser), further demonstrating some action in and around the environment:

The Steel and Titanium DLC pack will be releasing on the PlayStation Store on April 30th, which is nice to get solid confirmation on.
