THQ very recently passed down word that http://www.trueachievements.com/game.aspx?gameid=3538
would be receiving a new DLC add-on
. We also learned that the DLC, called "The Rock", would contain two new maps; Alcatraz and Bridge.
Today, the new DLC has been released and THQ has sent along a teaser trailer and several new screens featuring the content included in "The Rock".
"The Rock" can be downloaded right here
for 400 MSP. It does not add any new achievements to the title.
