(SPOILER)Yes, all of that was great. I died when the Gekko's ambush you while Raiden and Vamp are fighting. Its so difficult to play when they show Raiden and Vamp duking it out on the other half of the screen.

I also liked just going around Shadow Moses again. It was cool when they'd play certain voice clips from the original game as you went through Shadow Moses (it was even cooler when they let you play MGS1 for a while before you re-entered Shadown Moses). ARGH makes me want to play MGS1 again so much. Ill probably revisit it once Ive finished MGS4. Hope the last act doesnt disappoint. Its been so great so far.
