Mod «Battle Royale» for Hearts of Iron 4 (v1.9.0 - 1.9.1)

Welcome to Battle Royale! In this mod, countries will repeatedly declare war on and annex their weakest neighbors until only one remains! You can choose when to begin the chaos, to give yourself time to prepare.

Once the battle royale starts, all existing non-civil wars will immediately end with white peace, all puppets will be freed, all factions will be dismantled, all guarantees and military access will be removed, and every country will declare war on their militarily weakest neighbor, if any, or will navally invade a weak nearby country. Countries will now exclusively annex in peace conferences and will immediately gain cores on all owned states, while non-existant country cores (both releasable and annexed) will removed. AI countries will neither propose nor accept any diplomatic actions. Human players will be able to form factions among themselves, but they will be dismantled once nothing else remains. The last country standing wins.

Should be compatible with most mods. Bugs may arise from mods with events that repeatedly puppet, release, or white peace particular countries (Kaiserreich excluded).
