Significant changes from Cheesecan's Quicksilver:
- Mex layout is symmetric. Heightmap is approximately symmetric. The areas around 4 o'clock and 10 o'clock are most affected.
- Metal spots are slightly higher value. (Quicksilver is 1.5 per mex; this map is 1.7 to 2.2 depending on player count.)
- Water DPS is increased from 20 to 40.
- Fewer trees, and they should have mildly reasonable hitboxes.
