Mod «Tolstoy Engine» for Hearts of Iron 4 (v1.10.1 - 1.10.7)


THE WAR AND PEACE MOD or: "The Tolstoy Engine". This mod replaces the mechanics for War declaration (not implemented in the beta) and for Peace Negotiation.

The (beta) version is uploaded mainly for multi player playtesting.

The main differencences from the "standard peace mechanics" are:

  • Possible to ask for conditional surrender.
  • Harder to conquer a huge country in one go. So don't use if you are only playing for world conquest.
  • A few more peace options implemented, more coming soon. New ones done so far:
    • War Reparations
    • Oil Rights
    • Reduce Military Capability

Points are awarded for war type and surrender type. Costs for options varies with The world situation, the ideology of the winning country, and the stated war goal.
