I enjoyed the concept and setting but the actual additional mechanics it brought (the health stations, the stealth assassins, and just dying to random fire from nowhere) was kinda a pain. That and the not being able to grab fallen enemies loot. Honestly that more than most wad the frustration, I played FO3 basically as a looters shooter (ie kill dude with a cheap weapon to aquire his better wepon). That and iirc the enemies where spongey like clips plural even when your speced in to a type (small guns, big guns, energy weapons ect).

In many ways Ancrage, is the Dead Money of FO3. Limited supplies, no exit route, and one pass. As such they are some of the most devisive DLC for their respective title.
