Played through this with tale of two wastelands. Having the ability to aim down sights likely made this a more fun experience than the vanilla game.
There isn't much story as the only thing provided is the context of "the Chinese took Alaska!"
Fallout 3 isn't known for its shooting mechanics but the body dismemberment system still provides enough entertainment value from blowing off an enemy's head so that made this combat-focused DLC a neat and cheap experience. There should have been more implementation of RPG mechanics though. A more in-depth troop management system along with more ways to tackle the quests (especially the final boss!) would have added the depth that this expansion needs.
