Anyone else play this? I know this thread is like two months late but I started playing through it again and it really is an awesome game. Probably the best shooter I've played. I hope Valve decides to do the episodic content through Steam thing.
The last few levels are amazing. How awesome was it when you were staring out at the museum (or whatever it was) and you hear Breen's voice come on the loudspeaker: "I'd like to take a moment to address you directly, Dr. Freeman. Yes, I'm talking to you."
oh seriously! I thought the writing and the voice acting for that character (except for his bits at the end which i found 'meh') was totally brilliant.
Turns out the engine can only show one video overlay per runtime so when you're in the room where barney first reveals himself, and the professor comes on the video-screen, if you no-clip back into the docking area with the huge screen, here's the professor telling all of city 17 our plan!
