It's not just gunfire, stray rockets and armoured dinghies you need to worry about in Battlefield 4's waters. The Naval Strike DLC includes a hulking Easter Egg in the form of the megalodon shark.
This giant prehistoric shark breaches the water and crashes down upon players in the Naval Strike map of Nansha Strike. It can be triggered by 10 players treading water by a buoy.
The whole thing has been captured and posted by Youtuber Jackfrags for our terrified viewing pleasure. Fans have been hunting the megalodon for some time, and now it hunts them.
All we see is from the relative safety of the air, but it must be quite a sight down by the buoy. Naval Strike has finally been released on PC for Battlefield 4 Premium members after a delay.
