I wondered if in exchange for Gordon's services, the rebels were willing to share their break through with entanglement. Even the multi-verse spanning combine hasn't figured that out. I think the G-man would value that information.
I love the gunships. They are such a strange creature that looks like it was never meant to fly(it almost looks like a sea creature), but was forced to(it almost sounds like they're shrieking in pain when they take hard turns). The drop ships too. Some kind of crustacean-like creature that...
Hugh Laurie is too damn old. Freeman is 28. Other than that, its pretty uncanny. Rosario Dawson would be absolutely perfect as Alyx.
As far as Eli goes, here is my pick:
Clarke Peters from The Wire.
I believe that Shepard wakes up from the crash of his Osprey about a third of the way through Freeman making his way through Black Mesa. 15 or 20 Minutes in Shepard hears that emergency call for everyone to evacuate, where Gordon hears that same message 12 hours into the game.
When interacting with the rebels during Anti-Citizen 1, a rebel(I only recall the female ones doing this) says "I can't get this tune out of my head" and she continues to hum that very same tune.
Eerie stuff...
Hunters will definitely make a return. They attacked the rebels that located the Borealis in the transmition Judith sent. Plus a lot of work went into them to just have them appear in one episode, not to mention that they're pretty cool and interesting to fight.
I really like Shepard mainly because I like the way his story unfolded in Opposing Force. His osprey was shot down making for a very cool opening sequence, watching as your unit leaves you stranded, and learning that the black ops were the last resort of the government to end the Black Mesa...
After you destroy the automated guns in the scrap yard, Alyx says "Hey Gordon" not "Hey Boyfriend". Alyx fans hear what they want to hear though it would seem.
I think the reason for cannibalism is because the dead are a ready food source for the living. The combine aren't doing it to be sadistic perse. They are doing it because it is cheap and efficient. No need to grow crops, or raise cattle, or synthesize food. Think the Matrix and how the dead were...
