Experience Points (or XP) is one of the most necessary "ingredients". Players get experience from performing actions and completing mission.
As experience increases, players level up.
Experience is symbolized by a blue star.
It is crucial to gain XP in the game as many buildings have level minimums to purchase.
Some quests may only unlock at higher levels too.
The experience bar displays two things:
- In the bar is the amount of experience points. Putting the mouse on the experience bar displays the amount of experience needed to level.
- The star next to the experience bar displays the player's level.
