[Requires Carrier Battles Map Pack DLC] Start a Competitive match on Map 12 with a partner and set the victory conditions to 10 minutes and 1000 points. At the beginning fire a barrage of torpedoes at the targets, then submerge and proceed at high speed to distance yourself as far from the enemy as possible. Your partner needs to stay close to the fleet so the AI hunts him and allows you to disappear, but needs to avoid firing any shots. If your partner loses his submarine he will respawn and will need to instantly change to controlling the artillery (to prevent it from firing and scoring points) and then submerge and close with the enemy. The achievement will unlock at the end of the round.
