StingingVelvet: I honestly booted up the expansion, saw how they ramped things up even more, and then bailed. Maybe someday, but my tastes nowadays are more for slower paced shooters that focus on exploration and stealth. Actually my taste was always for that, it's just gotten even more so.
*maybe semi spoilers* The conclusion(and setup for the second expansion) is nice(albeit a bit predictable), and the lore and environments decent as well....that's a good part of why I persisted until I beat it....but yeah, it is a good deal tougher than a good number will care for.
That's why I say: thank the gawds for sentinel armor :)
(only available if one loses a few times during a boss battle afaik)
With that and putting the game on lower difficulties, the expansion becomes much more tolerable.
(minus the aforementioned gauntlets, of course)
Sidenote: If you never go back to it, i'd recommend watching the ending cutscenes online somewhere and finding a place to read any lore you didn't get.....it is quite nice.

Ontopic: If this game was in the arcades of old, it'd make people go through quarters like popcorn, I bet.
