About

Fallout: The Sum is a total conversion mod for Fallout Tactics: Brotherhood of Steel that reimagines the post-apocalyptic genre through an anarchist, utopian lens. Set after a global meltdown triggered by the "Sum" of every major anticipated catastrophe, the game offers a uniquely positive take on survival. It is a bilingual, single-player, non-linear RPG. You are not a hero, but an ordinary person trying to survive and carve out a meaningful existence in a hostile, toxic world. The story unfolds based on your choices, and you can end the game whenever you feel your character's journey has reached a satisfying conclusion.
