The Sum is a total conversion Mod for PC, released in 2017, blending Role-playing (RPG) depth with Turn-based strategy (TBS) combat. As a modification, it fundamentally alters its base game to explore a post-apocalyptic world reshaped by global warming, focusing specifically on the rise of various anarchist utopias. Players engage in tactical squad management and strategic positioning within this unique narrative framework.
This title functions as a total conversion modification built upon the foundation of Fallout Tactics: Brotherhood of Steel, shifting the established post-apocalyptic setting into a unique vision of the future. Released in late 2017 for PC (Microsoft Windows), it fundamentally alters the source material to present a new world narrative.
The core appeal of this project lies in its ambitious narrative direction. Instead of focusing on familiar factions, this conversion aims to explore a world reshaped by global warming and other catastrophic events, bringing to life a plethora of anarchist utopias struggling to survive and define themselves in the aftermath.
As a modification that completely overhauls the original content, this project retains the core gameplay loop inherited from its parent title: a blend of Role-playing (RPG) depth and demanding Turn-based strategy (TBS) combat. Players engage in tactical squad management, where positioning, cover utilization, and action point allocation are critical for success in engagements.
The experience centers on strategic execution during combat phases, supplemented by RPG elements that likely involve character development, skill specialization, and narrative choices that impact the player's standing within the various post-apocalyptic societies.
The primary differentiator is the thematic focus on societal reconstruction following widespread collapse. The narrative explores the emergence and existence of various anarchist utopias. This suggests a deep dive into ideological conflict, governance structures, and the challenges of building new societies in the ruins left by environmental and unspecified global disasters.
This modification is available exclusively on PC (Microsoft Windows). Since its release in 2017, the project has been presented as a complete experience built upon the existing engine framework. There are no officially documented downloadable content packs, expansions, or remasters associated with this specific modification project.
While the underlying engine and strategic framework remain rooted in the original title's tactical combat system, the entire context—the factions, the missions, and the world lore—has been replaced. Players familiar with the parent game will recognize the turn-based movement and combat structure, but the strategic challenges are entirely new, driven by the unique political landscape of the anarchist settlements.
