How to unlock the Double Edged Dagger achievement in LEGO Marvel Super Heroes 2 - Definitive Guide
So there are very few baddies in this level, but like most the boss fights Blackout will have an endless wave of henchmen. So basically just switch to Dagger (she is in the white costume) and kill the henchmen until it pops. Hope that helps somebody as I was taking my time and kept switching back to Dagger so I didn't miss any enemies, but that's not really needed. Happy Achievement hunting.
During the boss battle with Blackout at the end of the level, a constant stream of enemies will spawn one at a time. They will either come from the back, the back right, or the right. Just ignore whatever Blackout is doing and have Dagger beat up these enemies until the trophy unlocks.
This can be done as you’re playing Story Mode in this DLC level. At the end of the level there is a boss fight. As you are fighting the boss, endless enemies will spawn until the boss is beaten. As Dagger, instead of fighting the boss, keep defeating the spawning enemies until the achievement unlocks.
