Codes specifically designed to put you at the start of a difficult milestone, allowing you to practice strategy without the week-long setup. A Warning on Saving and Security
Save codes are very long; ensure you clicked "Select All" before copying.

Look for threads titled "Late Game Save" or "Import Codes." Sort by "New" to ensure the codes are compatible with the latest version of the game.
