青函省王牌攻城乌龟：白银

The Slam Target in the water should always be kept for last, as the turtle is very slow underwater. As the gunner can’t target objects underwater, the driver may need to hover over the surface of the sea before going for the last Slam Target to give the gunner time to shoot. Note that using Slam after getting in the water will make the turtle sink faster. Tips Regenerating ammunition Maintaining the highest speed possible at all times will generate more ammo. Leaving a few targets unshot to keep the speed up and coming back to shoot them later can be a good strategy. Using Bond of Vigor when out of siege ammo will rapidly recharge ammunition for its duration. The tier 2 turtle mastery, Slam Mastery will generate ammunition for artillery shots when the driver uses Slam. Ammunition regeneration can be further enhanced when using Slam if the driver equips a Turtle Pilot Booster. Using Overdrive after a Slam allows for much faster speed recovery and will save more time than using it just for the 10% max speed increase. The driver can equip a Mount Energy Booster and Turtle Pilot Booster to get more air time, which can help manage terrain or hover to go faster.
