Battlefield 2142 is a first-person shooter computer game designed by
Digital Illusions CE and is the fourth game in the Battlefield series. It is set in the 22nd century, during a new ice age.
The game was built primarily for multiplayer use allowing a maximum of 64 players on a server and allowing a single player mode with AI bots on Conquest mode with a maximum of up to 16 players. It has its own ranking system to keep track of the user's stats similar to the one used in its predecessor, Battlefield 2. It additionally opens up a new category of vehicles not seen in Battlefield 2 as well as new futuristic weapons the player is able to use. Battlefield 2142 has an unlock system allowing the player to choose a new unlock every time they achieve a new rank rather than making them purchase the item. EA Games has also released a booster pack called Northern Strike, which contains 3 new maps, 10 new unlocks and 2 new vehicles. At the 2007 WWDC, it was announced that Battlefield 2142 would be released for Macintosh computers in July 2007.[1] It was released on August 28, 2007 for Macintosh. Since the game uses Cedega it will only work with Intel based Macintosh systems and not PowerPC.



Gameplay
Battlefield 2142 does not use its own game engine[2] and is the first game in the series to not include the United States as a playable faction.[3] Battlefield 2142 includes two gameplay modes, Conquest and Titan,[4] the latter of which can only be played online in multiplayer maps. The Conquest mode supports up to 64 players online, while the Titan mode normally supports 48 due to performance concerns. However, the Titan mode can be modified to support 64 players as well. The single player mode consists of a maximum of 16 players, which include the 15 AI bots.
Battlefield 2142 features four different playable kits for the EU and PAC forces: Assault, Support, Engineer, and Recon. All of the kits have different weapon and equipment combinations, however they share several core weapons and abilities. The player is able to choose the armor type when selecting their kit prior to spawning. Heavy armor (the default) offers greater protection but reduces the distance that the player can sprint. Light armor offers less protection but allows the player to sprint further and recuperate faster.


Classes
Battlefield 2 had 7 classes while Battlefield 2142 has only 4. The class ablities from Battlefield 2 has been added up to 4 classes.
Recon: Sniper class and Spec Ops class put together. Assault: Assault class and Medic class put together. Support: Same as Bf2's support. Engineer: Anti-Tank and Engineer put together

Conquest
Main article: Conquest (gametype)
The Conquest mode involves two teams of players fighting each other while working to capture and defend spawnpoints, indicated by stationary flags, which change color according to the faction that controls them. There are several types of Conquest modes: Head-on, Conquest, Assault Lines, and Double Assault Lines. In Head-on, both teams start with one flag that can't be captured. Whichever team has the majority of the flags will initiate a ticket drain on the other team. The ticket drain is constant and cannot be increased by controlling more than a simple majority of the flags. In Double Assault both teams start with one base that cannot be captured by the opposite team. In Conquest, both teams start with one flag, that can be captured and play from there. In Assault Lines, the EU starts with one flag that cannot be captured, and the PAC starts with all the rest of the flags, in addition to one flag (called the Home Base) that can only be captured once the EU have taken all of the other flags. Assault Lines is only playable with Northern Strike. Double Assault Lines has only been seen as of yet in the 1.40 beta patch which included a 2142 version of the Battlefield 2 map "Highway Tampa." In Double Assault Lines, each team has a base that cannot be captured until all other flags have been captured. Unlike the Assault Lines gamemode, there has been no indication if there will be a new award for capturing the EU base. In all of the conquest modes, every respawn of a soldier takes one ticket.


Titan
The Titan mode involves players from opposing teams whose objective is to destroy the other team's Titan,[5] while trying to defend their own. Titans are massive heavily armored flying warships, which have powerful force fields protecting them from enemy intrusion or conventional weapons fire. As the force fields are up during the first half of a battle, players must fight to control the anti-Titan missile silos scattered about the battlefield on the ground. Titans can only be moved around the battlefield by the team's Commander. Each Titan has 4 anti-ground guns and 2 anti-air guns that, when used, will contribute to the fight on the ground. Occasionally, Titans are not moved at all, or very little, due to server latency issues, however, they can be (and often are) moved close together. Titans can be boarded by infantry via "assault pods" launched from an APC or from a rival Titan, by air-drop from a Squad Leader Spawn Beacon signal, or by landing an air transport on top of the Titan. The Titan can only be boarded in any manner once the force field is completely destroyed. Players must then damage the hull by either destroying four reactor security consoles and then the reactor core itself, or by continuing to control the missile silos that launch at the Titan. Both methods work together to damage the Titan. When the Titan’s hull fails, a 30-second abandon ship timer is triggered, alerting players to evacuate the Titan before the reactor explodes, taking the Titan and all aboard with it. However, the timer is never shown much to players' preference. During the beta release of the game, there was an award for those who managed to escape the destroyed Titan before the 30-second timer ended. In the retail game, the round ends when the Titan is destroyed, and because player deaths triggered by the end of a round do not count, the evacuation of the Titan had little significance aside from inciting a rush in the player. 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 a very precise timing to land on the ground, causing confusion amongst players initially.
