Mission Mode
Mission mode is the main single player mode in Protogem, it's comprised of one hundred rounds in total. This mode is where all ten planets can be unlocked for use in the score and online modes. There are also many different sets of both normal and special gems that can be unlocked by destroying the planets.
Each planet's ten missions are structured as shown:
Warm Up
Rounds 1 - 4
Warm up rounds are easy to complete because of the planet's low defense
Speed Run
Round 5
You must rack up a certain amount of damage before time runs out
Bonus Round
In this intermission, you try to intercept flying gems with your comets
Special Rounds
Round 6 - 9
On all planet's except for Earth, these rounds are where the special gems come into play
Endurance Round
Round 10
Both your comet power bar and the planet's health regenerate. Can you outlast the planet's defense?
