Here's the link from the article I got the info from: http://kotaku.com/5899485/rpg-classic-fallout-is-free-for-48-hours Here's the actual link to the download: http://www.gog.com/gamecard/fallout The download is windows only but I'm guessing you can run it through dosbox or boxer on Mac. I'll report back if I can! Also GOG is an authorized seller of the game so this is perfectly legal if anyone is questioning it. It's simply a promotion! EDIT: couldn't find anyway to open it in boxer or dosbox... maybe someone else wants to try to find a way?
Thanks for the heads up! Still have my Fallout CD, but added it to my account anyway! Anyone with a PC that likes older games should seriously check out GOG, they've got a ton of DRM-free older games that have been pre-tweaked to work great on modern OS's.
