The weapons you get after you finish the simulation are worth it. The campaign itself wasn't much fun.
The other DLC releases have been much better (The Pitt and Broken Steel).
Point Lookout, the newest DLC, is due out next week (supposedly).
Indeed, my Winterized Power Armour has not deteriorated since I got it which is Great.
Operation Anchorage has definitely been the weakest of the DLC.
I can't wait for the next expansion.
I am halfway through 29th level and I need more XP.
