[7][8] Battlefield includes two gameplay modes, Conquest and Titan,[9] the latter of which can only be played online in multiplayer maps (without using modifications ("mods")).

The player in the commander position has vital roles in the game, such as deploying UAV's, artillery strikes, airdropping supplies or vehicles for their team.

Conquest mode, similar to its predecessors, involves two teams of players fighting each other while working to capture and defend spawn points.

Players have the opportunity to reduce their number of lost tickets by reviving their "critically wounded" teammates with the Assault class' defibrillator.

Titans are massive, heavily armored, flying warships that have powerful force fields protecting them from enemy intrusion or conventional weapons fire.

As the force fields are up during the first part of a battle, players must fight to control the anti-Titan missile silos scattered about the battlefield on the ground.

During the beta release of the game, players who managed to escape the destroyed Titan before the 30-second timer ended received an award.

In patch 1.05, DICE reinstated the award for those attacking players who escaped the destruction in the "Titan Survival Pin."

However, receiving the pin requires very precise timing to land on the ground, causing confusion amongst players initially.

As with Battlefield 2, a key feature of the game is "Character Persistence", which saves and tracks almost every aspect of gameplay for players.

Each award (with the exception of medals, which are more for prestige, since they are the hardest to obtain) delivers a certain number of experience points, which go towards attaining a new rank.

A "Field Upgrade" is a temporary unlock which can be awarded to all members of a squad when they either kill, resupply, heal or revive a teammate while they are following an attack or defend order.

Combined with their increasing inability to find sufficient natural resources, the Pan Asian Coalition grows desperate.

Furthermore, early prototypes of Titans and other vehicles and futuristic technology were already in development in 2020 by the PAC in remote regions of Russia.

The rumors began in earnest following a February 2006 interview with Dan Blackstone, a senior producer from Electronic Arts, in which he mentioned "We're about to announce something very big, so stay tuned.

Early in the development process, the game was set on a different planet, as hinted by three moons in the sky in one piece of concept art.

In the Battlefield 2 Armored Fury Booster Pack map Midnight Sun, there was a drivable muscle car with license plate number 2142.

Additionally in Armored Fury, the drivable semi-truck had a magazine on the passenger seat that reads "Ice Age Approaches."

It was noted by many users that at the beginning of the beta the game worked great, but by the end it was horribly broken, with players getting stuck in walls and titans disappearing into thin air.

These travel ads sell the reader into going to the various maps, such as Verdun or Berlin, for £2142, with taglines such as "Gun not included" and "One-way."

Additionally there is a reference to the sci-fi film Starship Troopers, and by extension, World War II recruitment posters, on billboards featuring the slogan – "He's Doing His Part.

More recently in Britain (August 2007), the bank Lloyds TSB placed adverts in-game showing various accounts and products available from them.

For instance, an exploit that allows players to reach normally inaccessible locations such as high rooftops was remedied in the 1.25 update.

EA released an online-only standalone demo of the retail game, featuring the Sidi Power Plant map, with either conquest or Titan modes.

[22] Hyper's Kosta Andreadis commended the game for its "Titan Mode, refined reward and promotion system [and] well designed maps".

The PAC has set up strongholds in the urban areas left abandoned due to their constant assault, and the advancing ice sheets.

The booster pack contains ten new unlocks, three new maps, two new vehicles, and a new game mode called Assault Lines.

The booster pack was exclusively available through the EA Link for $9.95 US$; Since January 2008, Battlefield 2142 Deluxe Edition contains Northern Strike.

Most asymmetrical Conquest maps feature the PAC as the attacking force with the EU defending, whereas Assault Lines reverses the roles.

Northern Strike received "generally favorable reviews", albeit slightly less than the original Battlefield 2142, according to Metacritic.
