A new Easter Egg has been found in Battlefield 4. Introduced in the latest DLC, Naval Strike, it causes a Megalodon (a prehistoric shark) to appear.
On the Nansha Strike map, you need to find the Buoy near the main island (between flags A and B). Get 10 people in the water around the buoy. The shark will now appear, killing everyone in its path.
The MoGZ of War clan tried it last night (myself included) and can confirm all of the above!
JackFrags takes credit for finding this and you can see full details on his video…
