You have all day tomorrow and the rest of the day today to pick up Fallout, Fallout 2, and Fallout Tactics for FREE from GOG.com!

There are no strings attached with this. All you need to do is have an account at GOG.com and then hit up their special promo page for this deal, and proceed to checkout. The site and checkout are being hammered at the moment, so you may need to try a few times to get your games.
