Ok.
I'm pretty sure this is done now. I'm pretty sure I got everything.
Being that my short term memory is TERRIBLE and I tend to blank out at times, you're gonna wanna go through this and double-check just to make sure I didn't miss something entirely or do something stupid, but..... I'm actually pretty sure I didn't. I did this all pretty carefully. I didn't go over the ones you'd said you already did, though, so there shouldnt be any changes in those.
Again though, someone else has to do the multiplayer bit.
For the most part, all of these changes involved me editing what was already there, and outright removing things that dont apply anymore. The one spot where I added alot of stuff was the descriptions of the different mission types. Previously, it just listed a few examples, but, this being a wiki, I felt that most players reading it are going to expect a more comprehensive listing, so I listed and explained all mission types there.
There was alot of stuff to change overall, but it didn't take as long as I thought it would, so that's good.
EDIT: There are some formatting issues, the "contents" box for a couple of pages got messed up, and I couldnt figure out just why. Forgot to mention that earlier.
