this is a new bf2 based in the future watch the moviw and u will understand it all!!
http://www.youtube.com/watch?v=q_t6g0VLLY0 It's official, BF2142 has been in development for awhile and the video shown along time ago of a mech in a futuristic city was the new game. It's being made by Dice Sweden and is scheduled for release in 2006 (though that'll probably get delayed). IMPORTANT! The game IS using the SAME core engine as Battlefield 2.
There will be two factions (sad panda), American-European Alliance (Americas and most of Europe) and the Pan Asian Coalition (Russia, the middle-east, and India). These two factions are fighting over control of the only hospitable places left on Earth after the polar ice caps melt, covering 75% of the world in an ice age.
Apparently each base class will have two subclasses to choose from, such as support going engineer or medic. And you can develop the class "RPG style" as you progress, with a more extensive ranking system like BF2's.
Snipers and spec-ops are two paths to take in the "recon" class. There appears to be two sniper rifles. They have a cloaking ability that makes them appear like a blurry blob running around (when moving), when cloaked they are almost invisible. One of the branches carries tracking bugs they can plant on/near things which will put some kind of target on those enemies, and the article mentioned some weapons will automatically track/follow that target. They also get EMP grenades disabling vehicles and binding players.
Assault didn't get revealed too much except they have "badass guns", and the secondary fire on them launches proximity grenades (unless it hits someone/thing then it blows up).
Support you can choose from engineer or medic. Nothing revealed about medic, but engineers will have drones they can deploy which will spot enemy targets and attack with some light firepower, but it's made clear that it is a very loud obvious device that will attract attention to you. Also they will have access to 3-4 types of mines.
Anti-tank had really no info about it at all. PCG guessed the branches are anti-air and anti-ground vehicle, and their rockets might seek.
There are weapons still on Dice's drawing board such as a vehicle mounted railgun. APC's are equipped with emp weapons to help deploy under enemy fire, and have "mysterious hatches that might be used for experimental weaponry", perhaps customizable turrets or emplacements. The picture of the APC shows side mounted turrets and a top turret, with 4 little hatch-like things with logos that appear to be some kind of buildable area.
Infantry wear special uniforms that will allow for different abilities (recon has cloak).
Rewards will be given for excellent squadwork, and staying in the squad each map will have benefits.
Squad leaders will now deploy special beacons to allow squad members to respawn by him, so the leader will be able to join the fight while teammates are respawning unlike BF2. But the beacon can be destroyed, or camped until it's naturally destroyed.
New physics are being added to allow for more versatility with animations and such like the mech walking. They can also be knocked over in "extreme circumstances". It will also crush players.
New mines include the "chaser mine" which will be planted until a nearby vehicle drives by, at which point it will hover after it.
There are sticky-bomb like explosives for the recon.
Hovercraft-like things (think HK's from Terminator) will replace helicopters, and there will be futuristic fighter jets but Dice is keeping those under wraps.
The interface is being overhauled completely. Buddy list is being implemented that will allow you to join the server any buddy is in. Simplified menu is replacing the cluttery old menu. Also map loading times are being reduced.
Parachutes are being replaced with something Dice has not commented on. They did say though that they are not jetpacks. So it's something else.
Night vision/grappling hooks will probably show up in the game, they are thinking of importing expansion pack features into their game but they aren't sure what to do.
Co-op with your friends is going to be a complete new game mode, against an AI team.
There's another mystery game mode they are keeping under wraps but PCG is guessing it's an entirely air game mode (odd!).
Apparently the game was in a pre-alpha stage when PCG played the game but they said it should be out by the end of this year and the game will be displayed for sure at E3
