ANNEX 2179 extends the Acid Rain World into post‑war cities, ports and factories — places where supply chains and repair crews keep factions alive. Resource scarcity forces modular gear and kit‑bashing; people and machines work in small units, refitting armor and vehicles for the next mission.

The stories focus on scene‑driven conflicts and ensemble characters in the year 2179: logistics runs under fire, field workshops, black‑market exchanges and urban skirmishes. The tone remains grounded military‑sci‑fi with industrial textures and practical mech design.
