BRIGANDINE ABYSS Mission Mode
Twenty-four nations, unique victory rules, typically ninety-nine seasons.
Mission Mode is BRIGANDINE ABYSS’s sandbox war on Meltitea. Adglobe built it as a second way to play the same continent, not as a sequel map. Happinet and NIS America shipped it with the August 26, 2026 PC release and the August 27 console release. It is single-player. You pick one of twenty-four nations, each with a unique win condition, and you typically fight across ninety-nine seasons.
The six Story Mode campaigns are not extra nations stacked on top of twenty-four. Gran Dragnica, Scarlet Will, Mysteine, Purifanoe, the Samura Clan, and Pandemyuon are already inside Mission Mode’s twenty-four. Players who add six plus twenty-four and call it thirty unique countries are double-counting. Story Mode’s plot, Event Battle game overs, and automatic story recruits are covered on Story Campaigns. How the two modes differ at a high level is in Game Modes.
What Mission Mode is for
Story Mode is a narrative campaign with locked invasions until events fire, Event Battles that can yank any squads off the map, and about thirty hours per nation according to Game8. Mission Mode is the long board. Unique objectives replace “play this character’s story.” You still use seasons, bases, classes, monsters, and Rally. You do not play a second plot about Chaossolus killing Solginat’s king unless you choose a nation whose win condition uses Event Battle sequences.
If you have not learned the core loop, finish a Story Mode opening or at least read How to Play first. Mission Mode assumes you already know how squads move. The Campaign Walkthrough is written for Story Mode pacing; treat it as habits, not as a Mission Mode script.
Official nations you can name
Happinet’s materials list real nations. Use these names. Do not invent placeholder kingdoms that are not on that official list.
The six story nations appear here as Mission Mode slots as well: Gran Dragnica, Scarlet Will, Mysteine, Purifanoe, Samura, and Pandemyuon. Abyssloa is the empire Chaossolus declares after stealing the Brigandine. Ergennacht is a Nacht-faith holy order. Ragnelritter are punishment knights. Leshanna is a revenge village. Thousand Cane (also referred to as Southern Kane) is a crime city. The Shugen Clan are ninja and onmyoji rivals of Samura. Banlienshen is a commerce city that submitted to the empire. Alkis Sky Caravan is a sky-borne caravan nation. Ebony Fang are ash-wolf mercenaries. Noble Enhance are vampires. Kuklock are craftsmen and dolls. The Delzia Clan are dullahan. Kelmoon are centaurs. Centuria is a water-faith nation. Luon Hearts are pirates tied to a kraken. Glaudi is a mage academy. Akasha are desert tomb keepers. Talentis are lizardmen in scale armor. Brigand is the holy mountain of the Brigandine ore.
That is the twenty-four: six story nations plus those eighteen. The Faction Overview describes the six as Story Mode campaigns. This page is where the rest of the roster belongs.
Win conditions are the difficulty
Each nation has its own victory rule. Reviews of launch Mission Mode describe several kinds of objectives, not a single “conquer Meltitea” template.
Full map control is the classic paint-the-board win. Other nations must raise specific bases rather than hold everything. Some must sell items. Some must repay debt every season, which turns the economy into a clock. Some must collect every monster species. Some restrict which classes or characters you may use. Some compress the war into a twenty-season world conquest. Some are built around Event Battle sequences rather than a quiet ninety-nine-season grind.
Because the rules differ, there is no S-tier Mission Mode nation that is “best” in every save. A debt season that punishes slow expansion is a different puzzle from a collection quest. A twenty-season conquest is a different puzzle from ninety-nine seasons of map painting. The Best Faction page is about first Story Mode campaigns. Use Faction Tier List only as a companion after you know the win condition you actually drew.
How this relates to Story Mode
Story Mode still matters for lore. Chaossolus, Solginat, the Brigandine, and Abyssloa are the crisis the six campaigns answer. Mission Mode lets you sit in Abyssloa’s chair, or in Banlienshen’s submitted commerce city, or on Brigand’s holy mountain, without turning those identities into extra Story Mode protagonists. Saya’s Samura campaign and the Shugen Clan’s Mission Mode slot are related by rivalry, not by being the same save.
All twenty-four Mission Mode nations are available without finishing Story Mode first. The game is still single-player. For a launch-week take on whether the sandbox is the main course, see the review.
