Fallout 3

Fallout 3

Game Cheats:
Brahmin Tipping
If you come upon a wild Brahmin anywhere in the wasteland (not a pack Brahmin) crouch and hit the interact button to tip the Brahmin.

Alien and Alien blaster
From the Minefield head north. Keep going and you'll eventually pick up a radio signal from alien space craft. When you find it there will be a space craft and special gun with limited ammo somewhere in the area.
Easy experience points
When creating a character, tag the Speech skill. After exiting Vault 101 and reaching level 2, put all your skill points in Speech. This will allow you to easily exploit the glitch. Go to BigTown, located just east of Arefu. You may need to go to Megaton and speak to Lucy West to obtain the Arefu marker if it is your first run through. Talk to everyone in BigTown, leaving Pappy for last. He has a "Speech" option that remains for the duration of the game. Every success you get using the "Speech" option will net you 6 experience points. Multiple successes will stack, leading to larger point gains. There is no need to wait for fear of losing experience points. Just continue to use the "Speech" option until you level. You must stop talking to him to distribute points. Save the game after leveling up each time, as the game has a tendency to glitch which cause the loss of all your progress.

Have Fawkes and Star Paladin Cross as your followers at the same time
Play until to the point where you meet Fawkes. After he is freed and gives you the G.E.C.K, leave and do the Raven Rock quest. When you see Fawkes outside, tell him to be your follower then proceed to the Citadel and talk to Star Paladin Cross. When she says "I have something to ask you", respond with the second answer. She will say you have a wry wit like your father and ask to join you. Say that you would be honored and she will automatically join you. You now have both Fawkes and Star Paladin Cross as your followers.

Wear up to four head gear items at once
When you acquire the Chinese Stealth Armor, equip it then select up to four hats (for example, Eulogy's Hat, Winterized Power Helmet, Shady Hat, and Ledoux's Hockey Mask). When you have the desired hats you can equip any armor desired. Do not unequip the hats or you will have to do the stealth armor trick again.

V.A.T.S. Spotting
If you?re heading into seemingly-hostile territory or simply want to survey the area around you for enemies you might not yet see, try hitting the VATS button over and over again as you make your character turn around, searching all angles. Doing so will alert you to any enemies you may not yet see by zooming in on them in VATS mode. You?ll realistically be unable to do damage to your foes from such a distance, but it?s a good way to spot foes before they spot you so you know what you?re getting yourself into before the crap hits the fan.
