Super Mutant Behemoth Locations

When the Super Mutant Behemoth's have been found and killed they will not spawn. They can be found at the following locations.

Evergreen Mills:
Behind an electric enclosure beside the train tracks at the bandit camp near Vault 112. When the generator powering the enclosure is destroyed the Behemoth will escape.

Takoma Industrial:
Located east of the GNR Building at the end of the map. The Behemoth is just north of the factory, standing in the middle of some wrecked cars.

Jury Station:
Go west until you find a group of crumpled up train cars. Search this area until the Behemoth appears. You will know if you are in the correct area if you see a teddy bear in a shopping cart.

The Capitol Building:
Use the west entrance and go inside the main room. Look on the map. The room is straight down the hall from the entrance. However debris will force you to find an alternate route there.

Galaxy News Radio:
This Behemoth will destroy a wall just outside the GNR Building as you enter the area (Quest related).

Broken Steel Secret Weapon - Tesla Conon (Prototype)

You’re actually not supposed to get it since it was a developers tool, but this video breaks you from the Matrix and sends you “flying” straight to all the awesomeness.

There’s a hidden weapon to be found in the area of the Sattelite Relay Station. After Liberty Prime has smashed a hole in the building, walk past this hole without entering the actual hole, and walk past a few pipes. Check the rocky ledges to your right, just around the corner. Well, we’re going to have to climb that in order to reach the hidden weapon - which was probably used by the developers to test the new Tesla Cannon in Broken Steel.

To climb this ledge, jump on the ledges and press forward as much as you can. Save your game and reload this savegame. While the game is loading, rapidly tap jump and press forward. If done correctly, the game allows you to jump while you’re standing on the ledge, and you’ll climb a bit higher everytime you do this. It won’t work everytime, and you might want to change direction every now and then, but you’ll eventually reach the top.

Simply head past the sattelite towers, ignore the glitchy terrains and move back to the beginning of the area while staying on the higher ground. The Tesla Canon can be found on a table with three ammo boxes next to it. While it’s pretty much the same device as the Tesla Cannon, it looks like a Missile Launcher and expenses Missiles as ammunition.

Finding Dogmeat

You can find Dogmeat at Scrapyard which is North East of Megaton across the river (On the world map, Scrapyard is in the top right corner of the square that is two squares directly below Minefield). When you locate Dogmeat in Scrapyard save him from the raider and then ask him to join you.

Infinite XP

If you have the unpatched version of the game then this cheat will work. What you have to do is get your Speech skill up tp about 30 and go to 'Big Town' which is located north of Vault 101. Talk to the girl called Bittercup who will tell you about her dating exploits and then go to the house which is marked 'Common House' and talk to the man named Pappy. There will then be a speech skill dialogue option that says 'You came here with Bittercup, right?' and every time that you click it you get XP. Keep repeating this to get as much XP as you want.

Weird vault 106 glitch

When I was exploring vault 106, a blue screen came up. (like in new vegas you eat buffots or whatever and screen goes black and white) and it was a vision of the vault's first days. Now through out the vault you will find crazed survivors who will try to kill you (one of the people has a chineese soldier's sword) watch out for this guy. At one part there is a vision of like 4 different dads walking in a lab telling you to get out. Then there is a bunch of amatas telling you to run. The first is a vision at the entrance and it is all of your vault friends trying to find their quarters and the last is in the labs and it is a bunch of terminals with messages (the vision will not go away 'til you have read all of the terminal messages) and this is all I no so far. :D happy glitching :D

Weird ammo/weapons glitch(no idea how I did this)

So I was playing fallout 3 and I killed 3 raiders outside of the super-duper mart(do moria brown's quest in megaton to find this place) and 2 of them had alien blaster ammo.
And the next, when I was at paradise falls (the slaver company) I killed almost everyone there and waited 3 reality days then played again and had a weird weapon called methanol or something with all of the ammo.

Well here is some Raider Hideouts: Cliffside Cavern is right of Tenpenny Tower, Springvale School is above Megaton, and inside the Super Duper Mart is right of Megaton. I hoped this was help full.

Twilight zone tv show reference?

In the mother ship Zeta add on in the Captains record 25 the guy getting captured is talking about tv shows and he says that he wouldn't care if he is in the alien zoo. There was a twilight zone episode where aliens tricked an astronaut into becoming a zoo animal.

Where to find a Deathclaw?

Some Fallout players may have not heard of a deathclaw. It is one of the many creatures. Want to find one? Walk out of Megaton, circle around it from the right or left, and then you should see 2 or 3 deathclaws.

Make entire towns have themes!

Okay this is one of my favorite things to do for some reason :P First off you need LOTS of caps and ammo, A VERY high sneak skill "The Chinese Stealth Suit helps". And the will to have VERY bad karma. >:3 First you need to buy ALOT of good weapons "Chinese Assault Rifles,Combat Shotguns,Handguns,Nothing too big like flamers or rocket launchers" and ammo. And second the armor or outfits of your choice Then go to a place like Megaton and sneak around and pickpocket everyone you see placing weapons and ammo and armor each time.SAVE EVERY TIME YOU SUCCEED! and before you know it the ENTIRE city will be filled with people dressed in brotherhood powerarmor,Sexy Nightwear,Or Raider Armor! "Please note that the npc's will ALWAYS begin carrying their new weapons in their right hand no matter what their size due to a glitch so large weapons will be glitchy and most melee weapons just wont look right Your karma will be very bad if you do this too much but SO WHAT?! THIS RULES! =D "Ps take any ammo that the npc's are already carrying or they might not use your gun. And this tactic can be used on ANY friendly npc even followers! -Minus Dogmeat&Fawkes."
