Battle Royale

Battle Royale v3.0.7

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).

Enjoy!

FAQ

Q: Is this compatible with mod X?
A: Hopefully! I am trying to make this compatible with as many mods as possible. Please test it and let me know!

Q: How does this work for island nations?
A: They declare war on weaker nearby countries as well, if they have at least one division and one ship (i.e. can do a naval invasion). There is extra weight given to targets without any divisions, since amphibious battles are challenging.

Q: What happens to puppets?
A: All existing puppets are freed. Countries are banned from puppeting in peace conferences. Any puppets acquired later (through events and focuses) are freed if they have an army, and annexed otherwise.

Q: Is this good in multiplayer?
A: Hopefully! I’ve tried to limit the amount of time players have to spend waiting in peace conferences. Now, multiplayer games will now no longer pause for everyone unless 3 or more human players are participating in it as victors. Also, I’ve allowed players to spend almost all of their war score in peace conferences, reducing the need for passing.

Q: Can you delete the major focus trees,and delete national spirits?
A: Probably not in a way that ensures mod compatibility, sorry!

Q: Can you disable all the war popups?
A: I don’t think so; I think those might be hard coded into the game.

Q: Does it auto declare war on your puppets that you got after battle royale started? Or even faction members you added after the battle royale started?
A: The war declaration event does not check for puppets (though puppeting is now disabled, and other events check for them already). It does check for faction members though.

Q: How the mod define the weakest nation? Is it based on industry?
A: No, it checks the relation of army strengths with a country with the strength_ratio condition (also used in determining which mobilization laws are allowed in the base game)
