OK, I found a couple of bugs. Minor stuff in the grand scheme but I haven't seen anybody else post them:

1) In the Switzerland mission, in the control room for the ice drill, there is a computer. Hack it with a multi-tool. I've got the English edition. Both messages are in French. My French isn't nearly good enough to figure out what they mean. (New Game Plus)

2) I finished the game and saved the delegates by virtue of having the neutralizer. After Brown walks off with the delegates, I get a static back-drop. No epilogue, no credits - just a mishmash of what look to be bits of photos of a wooden frame of some kind. At that point Escape gives a menu with three options. Resume (watch the photo some more), options, and exit to main menu. (New Game Plus)
