Most of the gun games you play are located on land or in air, but what about in the water? Your mission is to defend the water world; of course you need to be there. A water tank is provided to indicate how long you can still stay under water. Movement will consume water and gravity will constantly pull you down, if you reach the bottom its game over for you. But worry not; water supply can be collected around you to refill some of the water in your water tank. Shooting off would also use water so just for a tip, use a smaller charge on close range to save water.
