Battlefield 4 Naval Strike DLC images have been leaked on Reddit just weeks before the expansion was set to arrive.

The images reveal the four new maps along with some of the vehicles used in the DLC. The screen shots can be seen here.

Naval Strike's Carrier Assault Mode will be a throwback to Titan Mode in Battlefield 2142.

The DLC will take place in the South China Sea, and involve two teams attacking each others aircraft carriers, reported Polygon. The battle takes place on three fronts.

"Both teams start on their own carrier and race to control the missile launchers placed on the map, by capturing the control points near them," Gustav Halling, gameplay designer, wrote on the official Battlefield blog. "This will automatically launch missiles towards he enemy carrier throughout the round, eventually destroying its hull and making it open for infantry attacks. When this happens for one or both teams, the carrier assault state is started."

He continued, "The team can then either drive a boat out to the carrier and climb aboard, or use the parachute spawn points above it. Once inside, the team must destroy two M-COM stations, which will open up new areas to the carrier, with the engine room being the final one. Destroying the two M-COM's, or bringing down the carrier hull's health to 0%, will win the match for your team."

"Battlefield 4 Naval Strike takes the dramatic water-based combat introduced in Battlefield 4 to four all-new maps set in the South China Sea. Take control over new weapons and gadgets, pilot the new hovercraft vehicle, and experience the Carrier Assault game mode in this intense expansion pack. Read on for details and the first official screenshots.," wrote DICE on the Battlefield blog.
