Game rules

From Surviving Mars Wiki
Jump to navigation Jump to search

Game rules are available to select at the start of a new game, and can be used to tailor the game to your liking. The rules may make the game easier or more difficult. Many rules may be selected simultaneously, but some are incompatible with one another; currently "No Disasters" and any rule increasing the disaster levels. Some rules will disable the ability to unlock achievements.

Game rules are utilized by Creative Mode and Challenge Mode to tailor the game play.

The difficulty challenge level will never drop below 100 %, the most difficult setting you can get from these rules (excluding terraforming) is 600%. Keep in mind that the difficulty rating will be affected by the map you choose as well.
