Kill a brute while it's charging you.
How to unlock Eye of the Hurricane
You will be introduced to the Brute enemy during your mission on Palaven. This is the first main story mission after visiting the Citadel for the first time. As you are killing husks with a turret defending a barricade, your next fight will be against this monstrosity. Wear down the armor first, and try to avoid the husks that are also attacking. When you get it to 1 bar left, wait for it to charge at you. When it does, shoot it with your most powerful power or weapon. If it dies and isn't charging, you can try to let the husk enemies finish you off so you can restart the battle. These also appear online in the later waves if you miss them all in the campaign.
