Seven war records, finally united in a single campaign.

A sci-fi turn-based strategy simulation that marks the final chapter of the "Heart of Steel" series.

The characters, battlefields, mobile armor, and battleships,
and the traces of choices accumulated in each game, previously scattered throughout the series,
collide across 30 strategic bases spanning the moon, low-Earth orbit, and Earth.

*** At the end of the series, decide the "outcome" of the war.

Early local wars, covert missions, confrontations on the lunar front, ceasefires and rifts in neutral territory, fleet command and special operations—
the fragments of the war covered in the previous seven games are now integrated into a single, all-out campaign.

In this installment, you are no longer a commander solely responsible for the survival of a single platoon.
You are the ultimate commander, managing the front lines of your entire force, recruiting characters, controlling sea routes,
and even shaping the post-war order.

***The core of the final stage of the "Heart of Steel" series

■ An all-out war that integrates the worldview, characters, and military power of seven series.
Characters and battle themes from previous games
are reimagined as campaign episodes and flow seamlessly into a single narrative.
Fans will experience the resonance of "Ah, this battle and this character lead here,"
and even first-time players will naturally understand the worldview as they follow the campaign.

■ An all-out war between three forces surrounding 30 strategic bases
The battlefield isn't just a map.
30 strategic points across Earth, low-orbit, and the moon each have unique roles,
and victory is determined by supply, blockade, checkpoints, maintenance, and route control.

- Empire: Fortification and blockade, a robust operation centered on order
- Alliance: Mobile warfare and joint operations, expanding the information warfare base
- Lunar Route Control Alliance: Controlling the tempo of war through route control, contracts, and a salvage economy
Victory is not simply about defeating enemies, but rather about controlling the route, maintaining supply lines, and securing all bases first.

■ A "Heart of Steel"-style structure where choices outside the battlefield change the ending
The "Heart of Steel" series' strengths—character relationships, choices, and branching endings—remain core to Total War.
This time, the scope has expanded.

Relationships with the Queen, Princess, Commander, and Wandering Captain/Pilot,
Prisoner handling, recruitment, contracts, and court/internal decisions—directly impact frontline operations and the faction's ending.

In other words, Total War is not simply a compilation of battles from the series, but the final chapter, expanding the "weight of choice" accumulated throughout the series into a strategic system.

■ A grand epic series completed in Campaign Mode
The campaign is not a simple tutorial.
Based on events from the previous series, you'll experience the war's beginning, spread, rift, three-way war, blockade, and final battle step by step through reimagined episodic battles.

Following the story,
you'll ultimately face questions more important than "who won."

What will you leave behind?

With whom will you build a post-war order?

*** End the series' final war, your way.

Love and War, Secret Mission, Tides of Tranquility, Moonlight Confrontation, Imperial Valkyries, Heavenly Commanders...

At the end of all these records, only one thing remains:

Total War.
