The Steel & Titanium Pack delivers two new multiplayer maps for Killzone 2 for the price of $5.99. The new maps, Wasteland Bullet and Vekta Cruiser, take place on a pair of speeding freight trains and a massive airship, respectively. While both maps nail the chaotic, war-torn atmosphere of Killzone 2, they are a bit more constricted than most of the other multiplayer maps. Each one is full of long corridors and small to midsize rooms that encourage intense, close-range firefights and prolonged battles for key chokepoints. The action is fast and furious, but it also feels a bit strategically limited due to the smaller layouts. A few unique touches help flesh things out, and jumping between trains in Wasteland Bullet is a thrill in and of itself. With a handful of new trophies to round it out, the Steel & Titanium Pack is a no-brainer for folks who still play Killzone 2 online regularly. If you haven't gone back to Helghan in a while and want a more detailed analysis of the pack, read on.
