As Iron Man you have 2 ways to use your micro-missile-barrage. One of them is while you’re using your hyper-velocity and the other is after activating armor overdrive.

What a lot of people don’t know is that they don’t share the same cooldown. So you can shoot 2 micro-missile-barrages back to back if you want.

For that i recommend to go to your settings and activate “hold to perform hyper-velocity. That way you can just tap your hyper-velocity key for quick bursts of movement.

All you have to do now is tap hyper-velocity then instantly shoot your missiles, then activate your armor overdrive and shoot your missiles again.
