How to unlock the Champion of Praxor achievement in Novastrike - Definitive Guide
Simple enough, just finish the second stage and use the same Strategy as you used for defeating the Falchion. You can ignore some of the objectives as well, you'll fail the objective but you'll still advance to the next stage.
