I'm not just talking about the ability to rip off someone's head, spine still attached. The game's settings are all inside buildings with few lights, at night, in the jungle. So, you know, dark.
That's great for setting the mood, but not so great for seeing just what the hell is going on.
In this video I give you a quick tour of the game's overwhelming night. Keep in mind that while the Predator has those spiffy visor views (many of which don't show up until a good chunk into play), and Aliens have pheromone tracking, your marine is left stumbling through levels with a cereal-box flashlight.
