Fallout 2

This sequel to the original Fallout is set in a post-apocalyptic era many decades after a nuclear war broke out and eliminated most of the world as we know it. America is turned into the Wasteland, a grim world full of ugly ghouls, powerful super mutants, mad robots and raiders, and various factions fighting for power. There are also many pre-war Vaults, some of which allowed their inhabitants to survive the war. The game uses an isometric view like most 1990s RPGs did, and the battles are turn-based.
