Core Gameplay

An arcade flight-combat game in the Ace Combat tradition: readable dogfights, large set pieces, a story told over the radio. Its distinguishing system is an enemy that fights the operator rather than the aircraft, and an intelligence layer that turns the in-world dossier into the player's progression.

1. Design Pillars in Play

Pillar	Mechanical expression
Hesitation is worth protecting	The Verify input; the prologue's override; restraint choices with real consequences (M05); the loop window in the finale
The enemy fights the operator	Operator Pressure and Load; ghost transmissions as gameplay events; HUD integrity attacks
Physics is the only thing it cannot redefine	Fuel rung state, power budget, discharge windows, altitude and thermal vulnerabilities
Know it before you fight it	The Intelligence Ledger: evidence collected in missions raises confidence grades and unlocks tools
The last human aces	Four distinct pilots with distinct signature mechanics; the circle between missions

2. Core Loop

Briefing (dossier pages, Ledger) 
   → Training (simulator drill scene, when scheduled)
      → Hangar (aircraft, loadout, parts, doctrine modules, optional drill, inspection)
         → Sortie (objectives, enemy, evidence collection)
            → Debrief (results, Ledger updates)
               → Circle (squadron scene, cohesion)
                  → next Briefing

The sortie is the center. The Ledger and the circle are the two outer rings: one makes the player smarter about the enemy, the other makes the squadron stronger under pressure. Every beat of the loop, cutscenes included, can change how the squadron and the enemy fly afterward (see Adaptive Progression).

3. Sortie Structure

Each sortie is built from these elements:

Element	Purpose
Objectives	Primary, secondary and hidden (see each mission document)
Evidence	Signatures, recordings and observations that feed the Ledger
Pressure events	Moments when the enemy targets a pilot's Load
Restraint points	Moments where the doctrinally correct action is not to fire, not to pursue, or not to break formation
Set pieces	One per mission, built around a single memorable image

4. Point of View

The player flies as different existing characters across the campaign (see Campaign Structure). Each POV changes three things:

Changes	Example
Aircraft and handling	Thorne's F-35C versus Marsh's F/A-18E
Signature mechanic	Command Picture, Edge, Read, Empathy display
What the enemy presses on	Thorne's orders, Marsh's helplessness, Asano's isolation, Eirhei's requests

The non-POV squadron members always fly as AI wingmen with their own signature behaviors.

5. The Intelligence Ledger

The Ledger is the in-world Strategic Intelligence Dossier presented as the game's codex and progression layer. It opens in M04.

Entries

Each entry is a claim about the enemy or the world, carrying a confidence grade: Confirmed, High, Medium, Low, Speculative, or Unknown. Entries are written in the cell's voice.

Raising grades

Evidence from missions raises grades. Examples:

Entry	Evidence needed	Grade change
EMP discharge window	Attack successfully inside a discharge window	High → Confirmed
RCS hotspot map	Hold aspect for 60 s of signature collection	New → High; Confirmed with thermal data
Port panel line failure point	Katya's analysis (story) plus thermal signature	New → Medium → High
Morgenstern illumination	Fire on the aircraft while illuminated	New → Confirmed

What grades unlock

When an entry reaches High or Confirmed, it unlocks a matching doctrine module in the hangar or an interface aid in the cockpit:

Entry at High/Confirmed	Unlock
EMP discharge window	Discharge-window timer on the HUD
RCS hotspot map	Passive-radar aspect overlay
Scream bearing	Audio direction cue for the scream
Port panel line	The faint marking used in M09 Phase 3
Pursuit is reconnaissance	Pursuit warning when closing on the aircraft outside doctrine

Unlocks never make a scripted outcome possible or impossible. They make the player's job clearer.

Permanent unknowns

Some entries can never be raised: subjective awareness; the meaning of let me go; the pistol. They remain Unknown at the end of the game. The Ledger states this plainly.

6. Difficulty

Setting	Changes
Story	Wider discharge windows; slower Load gain; Verify assists
Normal	Baseline
Hard	Narrower windows; faster Load gain; enemy uses its two discharges more aggressively; enemy carries more counter-adaptations between missions
Ace	Hard, plus no HUD integrity warnings: the player must notice instrument lies unaided; enemy adapts after a single use

Learning rates by difficulty are listed in Adaptive Progression.

The finale's Phase 3 window recurs on failure at every difficulty.

7. Modes

Mode	Contents
Campaign	Prologue through epilogue
Free Mission	Replay squadron missions (M01–M08) with any unlocked aircraft, using the squadron and enemy state recorded at that point in the campaign (or the Final Record after completion); interludes and the finale replay with their fixed aircraft
Ledger Archive	The full dossier, every entry at its achieved grade, all recovered logs and recordings

The MNZ-41 is never available outside the prologue.

8. What the Player Never Does

• Fly MINOZIS after the prologue.
• Kill a named character.
• Choose whether the aircraft is destroyed.
• Learn whether Anton is inside it.
