Levels

Overview
Player Levels show the players' progress in the game. Leveling up can be done by earning enough Experience Points to fill up the player's XP bar, which is featured in the "player badge" next to the player's avatar, in the top left corner of the screen. Gaining a level will empty the XP bar and will often unlock new Buildings, Units, Missions and/or Locations on the World Map.

Prestige
Prestige is something the player can achieve once the player has hit the current level cap (or MAX level). Once the player hit the cap, the player will need to fill up the player's XP bar one more time to enter Prestige mode (this currently takes ). The player will know if you’re in Prestige mode if your XP bar turns blue.

While in Prestige mode, the player can earn Prestige Stars for every time the player fill up the XP bar.

Stars can be used to get powerful units at the Prestigious Academy and Prestige Decorations. Prestige Decorations change with every major update so they are only available for a limited time. In addition, the player can trade Stars at the Hall of Bounty for XP, Bars and Gears.

When the level cap is raised again, the player's XP bar will revert to orange and the player will need to reach the cap again to enter Prestige mode.

Levels
The cost of districts can be found on the Land Expansion Chart. for each after reaching MAX.
