Hi,
Might have been mentioned earlier, but I'm not going to search through 68 pages to see if it has.
I just wanted to say that "the key to the north" mission is brilliant. Not (necessarily) because of what one has to do in that mission, but the combination of certain stuff happening _and_ (and that's my point) the music behind it at some point (being vague on purpose, don't want to spoil it).
This is the first time in a long time I think of making backups of local files (read: savegames) not just for backup purposes (I generally hugely dislike having to replay parts of games because of a lack of decent savegame management, hidden complaint there), but also for being able to replay a mission once I've finished it.
The combination of the music and the mission is just (both at some point, again, don't want to spoil it) great.
Just wanted to mention it, apart from all the potential problems, I thought it should be mentioned.
First time I used the "previous checkpoint" option just to replay/hear that.
Edit: get that single shot grenade launcher sidearm for the full experience.
