The Map Reroll Mod allows you to quickly randomize your starting map and steam vents locations. Your starting scenario, colonists, items, etc. will all stay the same.
Now includes the map preview generator–rather than trying for random maps, you can pick exactly the map you’re looking for from a nearly limitless selection.
Of course, there is a small price to pay–in the form of unmined resources from your map.
The resource cost is optional and can be disabled in the Options > Mod Options dialog.
The in-game description contains a brief guide.
Hope you enjoy.
Use your best judgment when rerolling, and make sure your game has been saved.
This mod has been designed to work with the vanilla game. Mods that include or affect map generation may not work or behave in unexpected ways.
