Answer first

What Is the Difference?
Story Mode provides six nation campaigns built around resisting the New Abyssal Empire. Mission Mode allows selection from 24 nations, each with its own objective and short story. Official examples include continental unification, base development, item or monster collection, recruitment, debt repayment, and base defense.
Key Takeaways
- Story Mode: six guided faction campaigns.
- Mission Mode: 24 nations and specialized objectives.
- Beginners usually learn systems more clearly in Story Mode.
- Mission strategy must follow its win condition, not default conquest habits.
Which Mode Should You Start?
Choose Story Mode when you want a structured campaign and a smaller faction-choice problem. Choose Mission Mode when a particular nation or objective is the main appeal and you are comfortable changing economic and military priorities around that goal.
Story or Mission Decision Table
| You want... | Choose | First follow-up |
|---|---|---|
| A guided first campaign | Story Mode | Beginner Guide |
| One of six faction narratives | Story Mode | Best Starting Faction |
| Access to 24 nations | Mission Mode | Mission Mode Tips |
| A specialized win condition | Mission Mode | Read that nation's live objective before moving or developing |
Mission Mode objectives can prioritize unification, development, collection, recruitment, debt repayment, or defense. Do not import a conquest-only route when the selected nation rewards a different result.
FAQ
Does Mission Mode have story content?
Official material says each of the 24 nations has characters and a short story.
Is Mission Mode only conquest?
No. Its objective list includes development, collection, recruitment, debt, and defense.
Can I change modes in one campaign?
Treat them as separate campaign structures and use the live save interface as the authority.

Confirmed Mode Scope
| Mode | Confirmed scope | Best first use |
|---|---|---|
| Story Mode | Six factions and their campaign context | Learn Organization and Attack phases with a clearer narrative frame |
| Mission Mode | 24 nations, each with its own win condition | Replay after understanding borders, troops, and base development |
Mission Mode is not simply Story Mode with a larger faction picker. Read the selected nation's win condition first, then route expansion and expeditions around it. Continue to the walkthrough for the shared turn loop.
Exact Mode Difference
Story Mode centers six nations with authored campaigns and faction narratives. Mission Mode expands selection to 24 factions built around objective-led win conditions. Use Story for a guided first campaign and Mission when the chosen objective—not narrative order—is the primary challenge.
