Wheel of Fortune - Looting the Fire Station
Leave the police station and cross over to the fire station. I suggest that you get ready for a very tough fight. When you go inside, you'll find a giant queen radscorpion. This isn't necessarily that difficult, but you need to bring her down quickly to save Logan and stay alive yourself. Use a good weapon with either armor piercing rounds or slugs, and consider using some chems to make it a bit easier. With Logan's help and a companion, it should end quickly.
The Legion soldier that set off the radiation attack is dead on the floor by the queen. Loot him if you want. I also suggest that you grab a few fire axes off of the rack along with a fire helmet, if you want one. There's nothing much on the first floor, so go up to the second floor. The main thing to do first, is to check the bathrooms.
In the bathroom, open the stall with the skeleton in it and look behind the burned remains. There's a unique fireaxe, called "Knock-Knock", behind it. You may have to move the skeleton to find it. When I repaired this with the fire axes from below and a few weapon repair kits, it was almost as good as "Oh, Baby" and a fair bit faster. A great weapon and your true reward for the quest.
I also suggest that you grab some medicine from the first aid kit while you're here, then go to the chief's office. You can hack the terminal to find out more history of Camp Searchlight, but you only need the gun and two grenades on the shelves. Take them and go over to the barracks.
There are four sets of computer parts inside duffle bags by the beds and two sets of radio parts on a table.
The last thing is inside the kitchen. Most of the food in here is irradiated, so just look for the pistol on the shelf and call it a day. Go back to Logan and report your success.
Unfortunately, Logan doesn't like to share. He's going to cut you out of the deal. You know what to do. Logan and his remaining mercenaries should actually be pretty hurt, poorly armored and poorly armed. Just shoot him a few times to bring him down. Once he's dead and the quest officially finishes, you should be able to loot the non-quest item versions of all the salvage. The grenade rifle is probably the most valuable, so it's a decent reward. Don't take the computer or radio parts though, since they seem to still be marked as quest items.
You're officially done though. Just take your new fire axe and loot and get out of the town. I suggest a quick trip to Novac for radiation treatment.
