For an escalating challenge, you may use the following optional difficulty ranking. The ranking system starts at Rank 1, which plays as the normal rules describe (with missions included). Each time you win a game, move to the next ranking. Each time you lose a game, move back to the previous ranking. Rank 6 is the highest ranking possible – do you have what it takes to achieve Senior Solar Sentinel status?

For each rank you have achieved beyond Rank 1, during setup, you must either banish one die or exhaust three dice. You must also draw and complete one additional mission for each rank above Rank 1, as outlined below:

RANKING:

1: Solar Soldier: Draw 4 missions and complete 3.

2: Solar Specialist: Draw 5 missions and complete 4.

3: Solar Sergeant: Draw 6 missions and complete 5.

4: Solar Staff Sergeant: Draw 7 missions and complete 6.

5: Solar Sentinel: Draw 8 missions and complete 7.

6: Senior Solar Sentinel: Draw 9 missions and complete 8.
