Like the base game, you are given more quests for your character to complete through the
Fallout 3: Point Lookout download. The base story starts when you are asked by a mother to find her daughter, which in turn, leads you to take a boat ride to
Point Lookout, Maryland, in an effort to find out about the missing woman, or at least information leading to her disappearance. From there, you end up visiting a ghoul-man named Desmond who is trapped in a mansion, fighting off members of a local tribe. After helping him fight off and eradicate the tribe members from the mansion, you eventually infiltrate their headquarters for information.
The core of the mission has you running back and forth across this little strip of Maryland in a seesaw battle between Desmond and the tribe, making decisions to ultimately sabotage one side or the other. The "man" behind the tribe is the brains of the operation, leading you to a showdown between you and one of the defunct beings.
While the gameplay of Fallout 3: Point Lookout is certainly enjoyable, I was admittedly a bit disappointed in the overall story behind this virtual game of chess. The storyline did accomplish giving the feeling of being caught in the middle, which is, of course, what it set out to do, however. I somehow could not avoid picturing myself in a situation similar to Bruce Willis' character in Last Man Standing.
In all, Point Lookout wasn't a super-long add-on, but did add a handful of gameplay hours to the original. It was great to be able to travel to an all-new location as well, but there wasn't a whole lot of new (or better, original) content. The biggest downfall of this DLC was that there was a lot of back and forth and no true need to discover new areas within the map. The bog section was interesting, but it was also repetitive as you kept facing the same (difficult) enemies over and over.
