Need a key to make an account for QW beta. Which are gone.
They'll let you DL the client, but you can't play without the key so....wouldn't bother.
And.....BF2142 demo really sucks compared to the full game. Which I believe is on sale for 20 bucks or so now. Demo has zero unlocks, and unlocks are where that game gets good. Demo was very un-fun...wouldn't have bought full version if I had not been in the beta and had some of the unlocks to know what a difference they make.
so then you have stat whores instead of those who help your team out. thats what i hate about the unlock system. ET has unlocks but they only last for the round/campaign. much better IMO
