Walking with Spirits

 is a Fallout 3 quest and achievement that is added to the game with the Point Lookout add-on. It is assumed that you will have to shave your head sometime during the add-on. Some time into this quest you will be drugged and you will halucinate and start seeing giant bobble heads. When the halucination is over you wake up with your head shaved and you will figure out that the tribals took part of your brain.

Walkthrough
You receive this quest from Desmond after defending Calvert Mansion from Tribals, Desmond asks you to infiltrate the Tribals to stop the attacks on the mansion. You must then find the Cathedral and talk over the intercom to a tribal so that you can gain enterance to the cathedral. So they send you in to see the mother of the punga plants and take the seeds. When you take the seeds  a gas sparys out from the fruit and your character falls over. But is not hurt so start to walk back but then it will look like your tripping on major drugs because of the gas. Ghouls that aren't really there attack you, Nuka-Cola quantum bottles fall out of the sky and explode, and (my favorite) revised versions of pip-boy bobbleheads show up with their own special messeges. Although it all looks scary nothing can hurt you. People you know begin surfacing from the bog, you see yuor Mom (yes the one that dide in the beginning) and then at the end you should see the megaton bomb and Mr. Burke leaning on it. Then you wake up after the bomb explodes and are given the achievement. After waking up you can visibly see a large wound on the left side of your face. You later find out that a part of your brain has been cut out of your skull. upon returning to the cathredal you have the option of getting the scar removed.

Reward
Access into the tribal's headquarters.
