Guides / Fallout 3: Game of the Year Edition
Oasis
Oasis is a lush, hidden settlement located in the northern mountains of the Capital Wasteland where a community called the Treeminds worships a mutated tree. Upon entering and participating in a purification ritual, you discover that the tree is actually Harold, a mutated human who wants you to end his suffering. You must navigate the surrounding underground cavern system to reach Harold's exposed heart and decide whether to kill him, stop his growth, or accelerate his spreading.

Tips
- Equipping gear or using chems with high Radiation Resistance is essential before entering the Sunken Chambers, as large sections are heavily irradiated and require swimming.
- If you destroy Harold's heart by burning it instead of crushing it, you will fail the Treeminds' quest objectives and turn the residents of Oasis permanently hostile.
