Mastery of Weapons
Achieve full mastery of weapons


Mastery of Combat
Achieve full mastery of combat


What to do for both Masteries.
Need to eliminate 1 enemy while boosting


and destroy 2 armoured vessels with missiles.


You should appear in Nimika Prime. Start side mission "Family Business" by flying/contacting Aryana (blue marker). Play it normally, until you reach the confrontation part. There you will have exactly 2 armoured enemies and 3 tiny ships simple enough to shoot while boosting.



The achievements should pop after all enemies dealt with.

Mastery of Rites
Achieve full mastery of Rites


What to do for Rites.
There's one left: Collision Course. Meaning you need to grab an enemy and throw it into asteroids. Three times.



You should appear in Stega Central. Fly around and the game will spawn enemies. Simply get close, seize them and launch towards meteoroids.

The achievement should pop after all enemies dealt with.
Success?!
