Hidden beside a building near the CN spawn point on the map "Dawnbreaker" is a small statue of the Peashooter from the game Plants Vs Zombies.

In the 17 minute gameplay reveal trailer is a scene in which the player must cut off their chief officer's leg in a quick time event. In the final game, this scene has been slightly altered, and the cut is made automatically.

A bowl of Easter eggs can be found in a hut on the 'Flood Zone' map. The hut is near the location of the C flag in Domination mode.

Battlefield 4 is currently banned in China due to its single-player campaign, which depicts a Chinese admiral attempting to take over the Chinese government and going to war against the United States of America in 2020. China has deemed this a threat to national security and also calls it a form of "cultural invasion".

A megalodon was rumored to be hidden somewhere on the multiplayer map "Paracel Storm", but players were never able to find it.

An Easter egg was later added in the "Naval Strike" DLC, where players can summon a megalodon by gathering 10 players around a particular bouy on the "Nansha Strike" map.

On the map Dragon Valley 2015 which is included in the Legacy Operations expansion, at the Temple (the H flag in a Conquest Large game), a small Phantom Program skull can be found imprinted on a pillar. If you stay near this pillar for long enough, a lantern adjacent to it will start flickering a message in Morse code. Deciphering the code will reveal a message written in Belarusian, which translated to English reads:


JJJU is the signature of Julian Manolov, an engineer at DICE Los Angeles who is responsible for several cryptic and elaborate Easter eggs in Battlefield 4's expansions and maps. This message's placement in a lantern was another clue. If you're playing on an unranked server, two or three randomized lanterns at the base of the temple will be lit every time the round starts. To turn on and off these lanterns, there are seven well-hidden interactive buttons scattered around the map, but which button controls which lanterns also changes every time the round starts. This is a pattern-based logic puzzle (similar to Parker Brothers' Merlin game "Magic Square" or Tiger Electronics' "Lights Out") that requires time and coordination to ensure that you turn on the correct switches to light all the lanterns without leaving any of them off. The solution included in the source of this trivia most likely will not work, as every time the round restarts, a different solution will be generated. Once you finally light all the lanterns, go back to the original pillar, and head to the adjacent pillar facing towards a tree. Within the side of the pillar facing the tree branches, a transparent digital keypad can be found. Pushing any button on this keypad will cause the lantern to start flashing an even longer Morse code message that reads:


This message directs players to the nighttime variant of the Zavod 311 map introduced in the Night Operations expansion, called Zavod: Graveyard Shift, where there is an old factory in the woods to the north of the map. In this area, you should eventually find a large rock where if you crouch and wait, a low-pitched, slowed down audio message will play that when sped up reveals a recording from the animated webseries "Battlefield Friends" of main character Neebs singing "I Got Little Birdy Legs", which he does whenever he captures an objective. Continuing with the instructions, the longest word in "I Got Little Birdy Legs" is "Little" and the word right after it is "Birdy". Simply multiplying the number of letters in each word together (6 x 5) only gives 30 which is not the correct code. Instead, the solution is to multiply each letter as its numerical value in the alphabet, which will look like this:


Inputting the above code back at the keypad pillar in Dragon Valley 2015 will cause the same Morse code lantern to beep twice indicating you entered the correct code, and then starts flashing a third Morse code message at a faster speed than the previous two:


Following these instructions at the water tower in Dragon Valley 2015 will cause another small button to appear, which will spawn another keypad on the water tower pillar. Entering the final code will trigger another clip of Neebs from Battlefield Friends screaming that he got "PROMOTED!" After the round ends, go to the Equipment and Customization menu and check your character's Camouflage. At the very bottom of the available camos is a new skin, the DICE LA camo. This is a unique, standout camouflague that was previously only available to employees at DICE LA until this Easter egg was implemented.
