Wave Breaker

Wave Breaker (Chinese: 波行動) is a map appearing in the expansion pack Battlefield 4: Naval Strike. It is set somewhere on rocky islands in the South China Sea, and features a naval base hidden underneath a rocky hill and an interactive submarine which can be dropped on opposing forces. The doors to the base can be open and shut via terminals controlled by infantry. They can be used to stop vehicles from entering the base.

Design Notes
"Wave Breaker has a unique submarine base hidden in the middle mountain which allows for tight close quarter combat, but it also has wide canals where it’s possible to do drive-bys with the attack boats to add extra mayhem to the mix. The middle area has many different Levolution possibilities. You can for instance bring down a submarine from its support and turn off the lights in the surrounding corridors. It’s also possible to stop boats from entering the area by closing the four flood gates and blocking the direct path from the bases on the two sides. The middle island will give players intense fights in Deathmatch modes."

Naval Compound
The Naval Compound is on an island away from the mountain. The area contains many stationary weapons for taking out boats with.

Submarine
The Submarine is hidden inside the mountain base and can be accessed by boat from the four canals, which can be blocked off using the gate controls. Infantry can get to the objective by walking into the base by the entrances at Living Quaters and Storage. The submarine's support poles can be destroyed by explosives and it will fall and crush anybody unlucky enough to be standing under it. This is the main levolution of the map. A square of water circles the construction area and can be patrolled by watercraft.

Storage
The storage area contains some containers that can be used for cover and an entrance for infantry into the submarine pen. Just inside the entrance, a fuse box can be shot and the lights in a room will go out. This objective also holds a launcher for carrier assault.

Living quarters
This objective is surrounded by some containers and is an entrance to the sub pen.
