Hot Zone" DLC doesn't come free with your EA Online Pass (the add-on is $10), saving $20 on a new copy of the game might help ameliorate your hesitancy to really heat things up. As its Video Game Deal of the Day, Amazon has dropped the price of Medal of Honor by a cool third to $40.
Additionally, EA has released the Hot Zone trailer -- embedded after the break. Apparently, the "Hot Zone" moniker is related to the DLC's new multiplayer mode, and not the possibility of the Tier 1 gang returning home, shaving their beards and hitting the town in crisp party shirts. Fooled again!
