Assault: The Assault and Medic classes from Battlefield 2 are
combined as the Assault kit in Battlefield 2142. The main weapons are
assault rifles with unlockable rocket or shotgun add-ons. Other unlocks include
advanced first-aid kits which can be deployed to restore the health of anyone
standing close to it, smoke grenades for screening, and a defibrillator for reviving
fallen comrades. The Assault kit's a helmet upgrade that allows the user to
determine what type of kit the enemy soldier is using, and assigns the
appropriate icon above the "enemy spotted" marker.
Recon: The Sniper and Special Forces classes from Battlefield
2 are combined as the Recon kit in Battlefield 2142. The main weapons
are sniper rifles, while there is also an unlockable carbine for close-range
encounters. This class can unlock a variety of explosives, including APMs and
remote-detonated RDX charges, both of which
can kill infantry upon detonation, and the latter can also be used for
destroying enemy vehicles, assets and strategic objects( SAT Track, UAV, Orbital
Strike and EMP Strike). Another unlockable item is the Active
Camo system, which makes the user 90% invisible to other soldiers, but if
the user gets too close to an enemy, the user can be easily spotted because of
the electronic and static sounds the Active Camo system creates. The Recon kit's
helmet upgrade increases the time the "enemy spotted" marker stays on the HUD.
Engineer: The Anti-Tank and Engineer classes from Battlefield
2 are combined as the Engineer kit in Battlefield 2142. The default
weapon for this class is a directable anti-vehicle rocket launcher. Other
unlockable main weapons include a high-velocity anti-tank rifle lacking guidance
systems and an anti-air missile launcher with guidance systems. The equipment
unlocks include motion-sensitive anti-vehicle mines, a vehicle repair kit, and a
defusing device for enemy explosives. While the other classes carry a pistol as
their sidearm, the Engineer class has a submachine gun to compensate for its
lack of an anti-infantry weapon. The Engineer's helmet upgrade works similarly
to the Assault kit's, but identifies and assigns icons for vehicles instead of
infantry.
Support: The Support class from Battlefield 2 remains fairly
unchanged for the Support kit in Battlefield 2142. The default weapon is
a light machine
gun. Unlike other weapons, this machine gun becomes more accurate the longer
it is fired. Other unlockable main weapons are a heavy machine gun and a
shotgun. The equipment for this class includes ammunition hubs, deployable
sentry guns, a sonar device to locate enemy infantry(Northern Strike only), EMP
grenades (useful in revealing nearby enemy Recon soldiers using their Active
Camo), and individual deployable energy shields. The Support kit's helmet
upgrade passively spots any enemy within a certain range that starts using the
Active Camo. The cloaked enemy's marker will appear on both the HUD and the
mini-map, and both will track as long as the enemy is within the Support's line
of sight.
