I wasn't expecting anything, especially not from my EB Games as they don't usually have preorder goodies, but they gave me this cool F.E.A.R. 2 booklet.  I haven't looked through it much yet, but the first page reads "GA EYES ONLY" and goes on to say that it's a briefing on the past events, includes personnel files on F.E.A.R. operatives and intel on Alma and all that.  At the bottom it says if you find this, not to read any further and to return immediately to GA, and in pen it says "or return to norton mapes in engineering" lol.  He also makes comments in pen here and there throughout the booklet.  One cool thing I noticed just now is a few pictures of the mechs, or EPAs (Elite Powered Armor), it shows one using a thermal imaging filter, which I didn't know it had.  It also has descriptions of each of the weapons, including a flamethrower.

Yes, the pre-order dossier is of incredible quality. I only warn that if you don't want spoilers to avoid reading it. It basically details the general plot of the game.
