Imagine if somebody took a vaguely classic-Tomb-Raider style of gameplay, and crammed it into the Star Trek setting. "Crammed" is probably too harsh sounding of a word, though, because The Fallen's actually great for it; the adventure-y puzzle solving meshes well with the decent (if not a tad clunky) third-person combat mechanics. The different levels inherent to whichever character you play as encompass an unique gameplay mechanic that one rarely sees outside of DmC.
