GameTap, the online video game distribution service, this week announced the availability of Interplay Entertainment's beloved 1997 role-playing game, Fallout, free of charge.

“It’s the year 2161, 84 years after a two-hour-long war that destroyed most of civilization. Mankind soldiers on, living out a hardscrabble life on the surface or holing up in great Vaults built inside caves,” reads Fallout's GameTap blurb.

“You’re a member of Vault 13 somewhere in Southern California, and the Vault Overseer’s got a job for you: find a replacement water purification chip within 150 days, or your home is doomed.”
