The mini-map, as well as the main game screen, shows symbols denoting three kinds of entities: blue for allies, green for squadmates, and orange for enemies, this applies to all interactivity on the battlefield.

The game's bullet-dropping-system has been significantly enhanced, forcing the player to change the way they play medium to long distance combat.

In addition, players have more combat capabilities, such as countering melee attacks from the front while standing or crouching, shooting with their sidearm while swimming, and diving underwater to avoid enemy detection.

The tactical binocular is similar to a laser-designator, in the sense that it allows the player to identify friendly and enemy units, weapon stashes, explosives, and objectives in the field.

At one point, Recker will briefly lose the tactical visor, forcing them to only use the Engage command to direct his squadmates on a limited number of enemies.

Also, the Commander can observe the battle through the eyes of the players on the battlefield, deploying vehicle and weapon drops to "keep the war machinery going", and order in missile strikes on hostile targets.

[9][10] The maps included in the main game are "Siege of Shanghai", "Paracel Storm", "Zavod 311", "Lancang Dam", "Flood Zone", "Rogue Transmission", "Hainan Resort", "Dawnbreaker", "Operation Locker" and "Golmud Railway".

Sniping mechanics also give with the ability to zero in your sights (set an aiming distance), and equip more optics and accessories than previous Battlefield games.

Another vehicle added in Battlefield 4 is the addition of the RCB and DV-15 Interceptor attack boats, which function as heavily armed aquatic assault craft.

[21][22][24][25][26][27] The Campaign also sees the return of Dimitri "Dima" Mayakovsky from Battlefield 3's Campaign—still alive after the nuclear detonation in Paris six years ago, and under the Chinese military's custody for unknown reasons.

Shortly after returning to the Valkyrie, Garrison assigns Kovic as head of the squad, and sends them to the USS Titan, a Nimitz-class aircraft carrier that had just been attacked, to recover its voyage data recorder before the wreckage sinks.

In his cell, Recker finds himself befriended by a Russian prisoner named "Dima" (a survivor of the Paris nuclear blast, now suffering from radiation poisoning).

Forced to make their way down on foot with privation, the group eventually finds a jeep and drives towards the US-occupied city of Tashgar.

During the journey, Hannah reveals how she lost her family to Chang's men after bringing Jin Jié to meet them, causing Irish to make amends with her for his behavior.

Learning the Valkyrie is within the region of the Suez Canal, Tombstone is airlifted to the ship, and arrives to warn the vessel that they are blindly heading towards Chang's navy.

Stopping Chinese forces from boarding the ship, the squad soon finds Jin Jié amongst other survivors, including Pac (who had survived the events in Singapore).

"[44] EA President Peter Moore announced in January 2014 that the company did not see any negative impact to sales as a result of the myriad technical issues.

[45] As a reward for players who bought the game early and continued to play it despite all of the bugs and glitches, DICE rewarded players in February 2014 with all-month-long, free multi-player content such as: bronze and silver Battlepacks, XP boosts and events, camouflage skins, shortcut bundles for weapons and additional content for Premium members.

The firm Holzer Holzer & Fistel, LLC launched an investigation into EA's public statements made between July 24 and December 4, 2013, to determine if the company intentionally misled its investors with information pertaining to, "the development and sales of the Company's Battlefield 4 video game and the game's impact on EA's revenue and projects moving forward.

"[47] Shortly thereafter, the law firm Robbins Geller Rudman & Dowd LLP similarly filed a class action lawsuit against EA for releasing false or misleading statements about the quality of Battlefield 4.

[49] In October 2014, Judge Susan Illston dismissed one of the class action suits' original case on the grounds that EA did not intentionally mislead investors, instead its pre-release claims about Battlefield 4 were a "vague statement of corporate optimism", "an inactionable opinion" and "puffery".

[60][61] Each one of these TV spots was narrated by a player of Battlefield 4 describing one of the unique experiences they encountered, along with a re-creation of the event using gameplay footage.

These events included things such as demonstrating the new Levolution feature, upgrades to gameplay, and unscripted moments that cannot occur in other games' multiplayer mode.

On May 21, 2013, DICE unveiled Battlefield 4: China Rising on a Battlelog post and stated that it would include four new maps (Silk Road, Altai Range, Dragon Pass, and Guilin Peaks) on the Chinese mainland, ten new assignments, new vehicles, as well as the Air Superiority gametype.

It involves dynamic combat on four new maps, Wave Breaker, Nansha Strike, Operation Mortar, and Lost Islands, which take place in the South China Sea and features a new mode called "Carrier Assault" inspired by Battlefield 2142.

[86][87] Evan Lahti of PC Gamer stated that although the game strongly resembles Battlefield 3 it still manages to remain "a visually and sonically satisfying, reliably intense FPS".

Joystiq's David Hinkle said that the game "drops players into a sandbox and unhooks all tethers, loosing scores of soldiers to squad up and take down the opposition however they choose".

[90] However, several reviewers noted that the multiplayer part of the game had been released with a lot of game-breaking bugs on PC, PlayStation 4 and Xbox One, such as server crashes and lag.

[101] During the first week of sales in the United Kingdom, Battlefield 4 became the second best-selling game on all available formats, only behind Assassin's Creed IV: Black Flag.

[104] The PlayStation 3 version of Battlefield 4 Sales in Japan however fell 84.148% to only 19,291 copies in its second week of release, and losing number one to God Eater 2.
