From the Producer of the original Fallout comes Wasteland 2, the sequel to the first-ever post-apocalyptic computer RPG. The Wasteland's hellish landscape is waiting for you to make your mark... or die trying.

The game is set in an alternate history timeline, in which a nuclear war between the United States and Soviet Union took place in 1998 in relation to an impact event involving a cluster of meteors that sparked a global nuclear war. On the day of the cataclysm, a company of U.S. Army Engineers were in the desolate southwestern desert constructing bridges in an area with a number of small survivalist communities and a newly constructed federal death row prison with light industrial facilities. The soldiers sought shelter in the prison, expelled the inmates, and invited nearby survivalists to join them shortly thereafter. Years later, together they formed "the Desert Rangers, in the great tradition of the Texas and Arizona Rangers", to help other survivors in the desert and beyond it.

The game begins in 2102, fifteen years after the events of the original Wasteland, with the Rangers now occupying the former Guardian Citadel, which had formerly housed deranged technology-worshipping monks (the Guardians), but is now fully under Ranger control after the monks had been wiped-out by the Rangers. The experienced ranger Ace is found dead by locals with signs of violence on his body. This greatly troubles General Vargas, the leader of the Desert Rangers. General Vargas, just a few days prior, sent Ace out to investigate a strange radio signal that speaks of "man and machine becoming one" while threatening to attack and wipe out the Desert Rangers. Controlling a squad of newly recruited rangers, the player is tasked with finding out who killed Ace and why they did it, and try to complete Ace's original mission.
