Sony just recently unveiled the Steel and Titanium DLC package for their critically acclaimed first person shooter, Killzone 2.  If you missed the announcement, the DLC pack contains 2 maps based on scenarios from the campaign, a broken down Vetkan ship and a train station.

Though Sony didn't mention a price point or release date, internet rumors have it that the map pack will be free and will apparently hit the PSN's digital shelves before the end of the month.  Tweakers.net claims the info comes from an e-mail Sony sent out, though we received no such e-mail.  We've contacted Sony for the official word, so until then, take this news with a grain of salt.
