Apologies for resurecting and older post, but it is very much so possible, you just need to search for "Dethklok BF2142" on google and click the "Spoiler - Old Info" button, and download the "Stats Redirected DirectDownload" this just routes the master server from the old one to a new fan-made one, which means you make an account easily via the game and then are able to play single player.
This is how I got my disk copy working before it broke but its how I play on origin now :D
Happy Battles!

Battlefield 2142 is working on Gameranger in 2018... Goto Battlefield2142.co for all the information to play on Gameranger. Single player is possible there as well as multiplayer.
