How to unlock the M.A.D. achievement in HUMANKIND - Definitive Guide
Pretty self explanatory, though you have to do this all in one game (from my personal experience). You will need to first make sure to choose the Nuclear Proliferation choice in the Nuclear Weapons civic and build missle silos at your cities to be able to house them.
Mind you, this can be done once a game is complete as long as you choose to keep playing and don't end the game.
