The expansion includes, among other things, some new guns. So if you get to the arms dealer, and you see an open box in the middle of the room with a silenced shotgun, a double-barreled shotgun, and a crossbow that shoots exploding arrows, you have the expansion.

The serial is for online multiplayer. If you can figure out online multiplayer, you will figure out where to put your serial.
