No Way, Nova Corps Achievement
No Way, Nova Corps15
Interrupt a Nova Centurion with Gamora's Call to Action.Chapter 7
During this chapter, you will fight against Nova Corps members (blue outfits). Around halfway through the chapter you'll focus on a bigger tougher Nova enemy that takes way more damage. This is the Nova Centurion (unfortunately, this enemy isn't added to your compendium, so I can't provide a screenshot).
As with all of the achievements for interrupting an enemy with a specific character's Call to Action, you need to weaken the enemy and fill up their Stagger meter. The best abilities to stagger enemies are Drax's abilities and Quill's Eye of the Hurricane ability. Once they are staggered, you will get a prompt while looking at them. Do so, and one of your allies will do a Call to Action. You unfortunately have no control over which ally attacks, so if it isn't Gamora for this achievement, you can reload your checkpoint to try again.
