Miss Launcher (Fallout 3)

The Miss Launcher is a unique Missile Launcher. It is comparable to a grenade launcher, as it has an arcing flight similar to the Fat Man. If used non-VATS it is excellent practice for the Fat Man, as you won't kill yourself with a badly placed shot (most of the time).

Location
The Miss Launcher is located in a weapons storage room inside Fort Independence. You will always have to pick the lock on the front door (unless you pickpocket Defender Rockfowl, Defender Morgan, or Protector Casdin); however, if you don't want to have to fight everyone inside it is recommended that the player completes the unmarked Outcast Collection Agent quest up to the point when Casdin will trust the player. Once you gain the trust of the Outcasts, you can kill the three outside to get all the stuff you gave in back. This will also give you the key to enter Fort Independence. This is not recommended, however, for players who plan to use Protector Casdin for equipment repair purposes (See his article). Once inside you need to go down to the lower level. There are two entrances into the basement. The first way is through an entrance outside that leads directly to the lower level. It, like the main entrance, is a hard locked door. The other way is to go through the main entrance and then proceed down to the lower level from the ground level. However, the second method will lead to a locked door that can only be opened with a hard locked terminal. The password is in the desk next to the door if the player does not wish to or cannot hack it. Once through the door, the two Outcasts guarding it will usually be armed with a Ripper and a Laser Rifle. Deal with them (if they're hostile), and then go to the research room with several computers in it. In here go to the computer in the corner; there is a file on the computer called "Research - Missile Launcher". Read the note and you will learn that the Miss Launcher is in the storage room (locked 100 skill needed). You can get the key from one of the footlockers in the bedroom (room full of beds). (The other computers in the research room tell you about the other projects e.g. Enclave Power Armor, Minigun, Plasma Rifle)

(Note: you can also fire at the door once or twice to alert those inside, once the door is opened you can charge in before the Outcasts have a chance to close the door behind them)

Bugs

 * Sometimes at close range, V.A.T.S. is exited before the missile detonates, negating the benefit of temporary 1/10 damage and potentially killing you. This close-range bug may also lead to freezing issues on the Xbox 360: the controller will remain rumbling and the console will freeze.
 * If you place this item in your house it may move and glitch into walls. In time, it will disappear from your house altogether.
 * It has been found that upon glitching into the 'void', the Miss Launcher will sometimes reappear upon re-entering the house.
 * If you don't read the note before entering the storage room the miss-launcher may disappear forever.
