A map gen preset with some features:
- Endless badlands with no water outside of starting area.
- Rare resources (one or two patches per 32x32 chunks).
- Radars have a small chance to scan a distant resource deposit.
- Resources in starting area are should be enough to build a train and a railroad.
- Biters are present, but rare.

You may experience some freezes and FPS drops for the first few minutes of the game - it is fine and they will stop completely.
Resources are not generated separately, but being chosen to be generated for each deposit, so decreasing frequency of one resource increases the frequency of others. E.g. 50% frequency of Stone means that 1/2 of Stone deposits will be "replaced" with other resource.
