When you reach a pinnacle of empire building, your faction rewards you with a star. Stars are worth coins at the end of the game.
Here are the ways to place stars, as shown on the Triumph Track:
When you achieve one of these goals, you must place a star on the appropriate space on the Triumph Track. You cannot lose a star after you’ve placed it. For example, if you place a star for reaching 18 popularity and you later drop below 18, the star remains on the track.
By default, each player may complete each of these goals exactly one time. Having a star on a goal does not prevent other players from placing their stars on the same goal.
Here is a descrption of each section on the Track:
Complete all 6 upgrades
Deploy all 4 mechs
Build all 4 structures
Enlist all 4 recruits
Have all 8 workers on the board
Reveal 1 completed objective card
Win combat (up to 2 times)
