Welcome to the swamp like place called Point Lookout.
Overall: This DLC is worth getting. There are a ton of sidequests to play in and a ton of new locations to locate in this game. The story in this DLC is a bit longer then any other DLC that you would play through. So it will last you a while to play in.
Overall:
Story: 8.3
Gameplay: 8.9
Graphics: 9.2
Music: 7.3
Overall: 8.5
