That combined with the action->creepy stuff->action->back to creepy stuff transitions that were sometimes very abrupt kept me wondering what was next.
I'm betting on "action".
I just completed FEAR and Extraction Point. XP was ludicrously disappointing in terms of story... excellent combat, and decent variety in the levels, but an utterly unsatisfying ending made the whole experience seem hollow.
I'm interested enough to pick up Project Origin at some point. I just hope Monolith do a drastically better job of continuing their storyline from the first game.
