10 Darkest Quests In Fallout History

7. Oasis (Fallout 3)

You can say what you want about the world of Fallout 3, but a bit of colour here and there wouldn't have hurt. Yes, we know it's called the "wasteland" for a reason, but after a while the endless sea of grey rubble makes for pretty repetitive scenery. However, all of those artistic choices almost make sense when you find one of the few flourishing parts of DC left in game; all in the aptly-titled location, Oasis. Because you've spent your time so far trawling through the same barren landscape, finding a place with actual colour and living, breathing plant-life provides for a welcomed change of pace. At first everything seems hunky dory at Oasis, and, initially anyway, the location more than lives up to its namesake. Of course, then the quest kicks in. One of the first "people" you see upon entering Oasis is a talking tree named Harold, who, as it turns out, was a fan-favourite Ghoul that featured in all of the Fallout games previously. By the third game he'd developed a virus that had overtaken his body and rooted him to the ground, with a select few people treating him as a god and forming a cult around his seemingly majestic being. Had enough of his static immortality, he tells you to put him out of his misery. However, doing so would ruin one of the only flourishing places in the entire map, so it's up to you to decide which course of action to take. Combine this choice with the increasingly crazy cult handing out mind-altering sap from the tree and it makes for one of the most disturbing quests Fallout 3 has to offer.
