Well I bought it thinking it was going to have a really cool campain, but I can't find even a campain, is it just strickly a multiplayer game.
There is a single player but no campaign. Sorry. I suggest you start with single player and get used to the keys then go out to the world of multiplayer.
Nah battlefield 2 is definitely the best. And battle 2412 is exactly the same as bf2 and how they play.
yeah any of the BF games are the best i play the BF2 ones and they are fantastic! the tanks and flight simulation with badges gives it a more realistic feel though i've never played 2142 but i think its safe to say its fantastic too and 1up would be playing it online
