EA’s much anticipated Battlefield 6 is here bringing with it the return of a campaign to the long running franchise. The campaign features 9 missions and has miscellaneous achievement for each mission. This guide will help you unlock “Deep-Six” achievement in mission 3 Operation Gladius.
At the very beginning of mission 3 you will be in a turret inside a boat/tank. As you head towards the beach with all your troops someone will yell out that there are mines in the water. In order to obtain the Deep-Six achievement you simply need to find 3 of those mines and shoot them to cause them to explode before they hit your, or another allied boat.

These aren’t too hard to spot so you shouldn’t have too much trouble finding 3 to shoot. They will randomly pop up out of the water a decent amount away from you so you have enough time to line up a shot.
That’s all there is to this one. Another simple achievement that you can miss if you aren’t realizing what you need to do. We will be covering Battlefield 6 extensively so check below for everything you need to unlock in the campaign, including the collectibles.
