SPOILER IMPRESSIONS:::::
Got it, finished it in 2 hours.
Impressions:
As a concept, it seemed to be interesting. exploring the chinese invasion and what would be pre-fallout Fallout.
It was there, but only as the VERY thin outline to what was a poor multi objective FPS mission. FPS is not what Fallout3 does very well (but it still works).
What Fallout does do well is allow you to explore some morality boundaries, especially in a world where the accepted framework of society has been burnt away, in the DLC we have NOTHING to do except use VATS and choose a loadout.
Maybe the exercise was to show players who complain about the failings of Fallout3, that this is the alternative

, take out all the 'Brown' and you get linear 'Ice Blue'.
The ending, where you can defeat the boss by having a speech over 50% is pretty pathetic, its not even a 'use your speech skill to enter into dialogue tree with General Tang', just one line, as bad as, if not worse than the President death.
3/10,
It didnt crash once, my evil character because neutral at the end of the mission, i got a sword.
