Infinite XP

When your speech skill is high enough (30 is recommended), go to “Big Town”, which is located north of Vault 101. Speak to the girl named Bittercup, and she should tell you about her dating exploits. After speaking with her, go into the house marked “Common House”, and speak to a man named Pappy. There should be a speech skill dialogue option that says “You came here with Bittercup, right?” You will get XP every time you click it. Repeat this as many times as desired. Note: This trick works in the unpatched version of the game.

Early detection

When wandering around the world or towns, use the following trick to get an early notification on enemies, encounters, or who is nearby. Keep tapping [V.A.T.S.] while searching at all angles. If there is something out there, you will get the V.A.T.S. zoom in with a low score. You will at least know what is there and can figure out a plan of attack or how best to sneak around it.

Finding Dogmeat

Dogmeat is found in Scrapyard. On the world map, Scrapyard is in the top right corner of the square that is two squares directly below Minefield. Follow the clear triangle on your compass if you are having problems finding it. Enter Scrapyard, and look/listen for fighting. Your will find Dogmeat fighting a Raider. Once the Raider is dead, you can talk to Dogmeat and ask him to join you.

Getting both rewards in “The Replicated Man” quest

When you discover the identification of the android and are deciding to turn him in or warn him, go to the android first. Convince him to go to Zimmer on his own, and he will reward you. After that, go to Zimmer in the science lab. Tell him about the android’s identity. He will also reward you. Note: You will still get bad karma.
