Oh, that's what counts as gunplay? I dunno, I saw people mentioning stuff like death sequences, how the gun sounded, how the gun shot, how the weapons handled, and so on in reference to "gunplay". Someone even mentioned laughing at the fact that you still see the gun out when Gordon swims.
That stuff has never really mattered to me all that much, but yeah, flow of combat and tactics are obviously important. That, I thought, centred more around AI, though. Of course, I could just be an idiot here. I've clearly been out of the FPS buzzwords loop for awhile. I'll refrain from commenting on anything until I figure out what the hell all of you are talking about.
