Fallout 3 Point Lookout DLC E3 Preview

Another E3-based preview of Fallout 3's fourth DLC add-on has surfaced on the 'net, and this time it's at GameSpot.
Speaking of the locals, we met some of Point Lookout's savage inhabitants as we made our way up the hill to the mansion. These half-clothed mutants looked like gnarly inbred hillbillies, the kind that might drag you away in The Hills Have Eyes. After making short work of those goons, we approached the mansion (Calvert Mansion, by name) and saw some high tech security cameras guarding the entrance. A voice came over the loudspeaker, identifying us "not a Tribal" and demanding that we get inside and help him fight some bad guys off. Inside the mansion we found ourselves in a large entrance hall, with two curving staircases framing a makeshift outpost. Wired turrets were blazing as a man and his two dogs fought off some characters that looked a lot like Raiders.

In Point Lookout, the Raider niche has been filled by Tribals, fervent cultists who paint their faces and utter religiously-themed battle cries. Playing as a Level 20+ character, we actually had a tougher time killing a few Tribals with a Chinese Assault Rifle than we expected. Point Lookout is more difficult than much of the previous DLC, and is tailored for players who have beaten Broken Steel and are on their way to level 30. In fact, we're told the initial message clueing players in to Point Lookout's location will include a warning that it is quite dangerous. The Lead Producer of Fallout DLC translated: players should be at least Level 17 or so, and even those in the early 20s will face a healthy challenge.
