One option pertaining to Rarity (how often they're dropped) and one option pertaining to Scaling (how much is dropped) for both, I suppose?
Something like:
- Alien Chunk Rarity (Slider = 1% lowest <--- 100% base ---> X% highest?)
- Alien Chunk Scaling (Slider <--->)
- Abandoned Warehouse Rarity (Slider <--->)
- Abandoned Warehouse Scaling (Slider <--->)
Then maybe a few toggle options like:
- Increase Alien Chunk Scaling with Biter evolution (On/Off)
I'm not sure what's best, but thanks for considering it!
