EA is celebrating the 10th anniversary of the Battlefield series, so they made Battlefield 1942 (the first Battlefield game) free to download on their website, along with more information.
FYI, The offer ends March 1, 2013, and is not on Steam

EDIT: Even though "Mac" is listed as a supported platform on the above site, the game requires EA's Origin to run, which isn't yet available on OS X
