Your RimWorld colony supplies the front with real equipment and technologies from your installed HOI4.
Build a military supply colony inside RimWorld. Choose Britain, the USA or France, claim starting supplies, build a hand-powered frontline armory and fulfil orders for rifles and herbal medicine. Earn silver and reputation, unlock improved equipment through research and defend your colony from retaliation raids.
This is a real bring-your-own-games mashup: it reads country names, initial civilian and military factories, infantry equipment and technologies from the player's installed Hearts of Iron IV while RimWorld runs. The mod converts that data to RimWorld's tactical scale using its own balance rules. HOI4's full strategic simulation is outside this first alpha.
Single-player, Windows x64. Both RimWorld 1.6 and Hearts of Iron IV are required; RimWorld DLC is not required. HOI4 supplies data and does not have to run as a second process. The bundled launcher enables the native mod in a separate persistent colony profile and includes its .NET runtime.
First playable alpha, tested on RimWorld 1.6.4871 rev591 and HOI4 Operation Postern 1.19.3.0.c01a (5632). Native crafting by a colonist, insufficient-stock rejection, supply delivery, payment, reputation, retaliation raids and save/reload have passed in the actual base game with only this mod enabled. A local installation from the final ZIP and normal launch without test flags have passed; Melty one_click_check is yes. The Melty client Play/install verification and publication remain pending. This is a short-cycle alpha, not a long-term balance or other-mod compatibility guarantee.
