Crystal Powder

[GammaPerfect]

What is the most reliable way to get Crystal Powder for the collector?

[DataNinja]

Your choices are extremely limited, since you need 3 (unless you decide to gamble with Lucky Luke):
1. Either Scrapyard or Rift (I prefer Scrapyard, since there's no clock to worry about)
2. Doom Gardens
3. Fusion Core

Can't do Pit, since you can only possibly get 1 crystal after that, and can't do Waste Station, since Doom Gardens spits you out after the entrance.
