1. Summary
Each of the five playable characters carries a unique loadout of four active abilities mapped to fixed hotkeys (A/S/D/F), covering melee takedowns, ranged attacks, distractions, traps, debuffs, disguises, area attacks, and companion support. No character masters all categories; instead, each covers a distinct tactical niche (infiltration, luring, crowd control, disruption, or long-range elimination). Abilities are introduced progressively via in-mission tutorial scrolls, and firearms are unlocked partway through the campaign. Character-specific movement, carrying capacity, and health further differentiate roles, forcing squad composition and cross-character coordination to overcome varied enemy types and environmental challenges.
3. Design Intent / Job Story
When planning a tactical approach to a guarded area, I want to use each character's unique abilities mapped to fixed hotkeys, so that I can overcome enemies through coordination and complementary skills rather than relying on any single character.
4. Role in Gameplay Loop
- Core combat and stealth interaction layer that distinguishes characters from one another tactically
- Drives squad composition decisions by restricting any single character from solving all encounter types
- Enables cross-character combo plays (e.g., distraction + takedown, trap + lure, disguise + ambush)
- Progressively expands through campaign: firearms unlock mid-campaign, new abilities introduced via tutorials
- Forces coordination between characters with complementary niches (infiltration, luring, crowd control, disruption, long-range elimination)
5. Preconditions
- Player has selected a character that is alive and not incapacitated
- The desired ability is off cooldown and has available charges/ammunition if applicable
- For reusable abilities (shuriken, sake bottle, trap), the item has been retrieved after prior use
- For disguise abilities, appropriate clothing has been acquired from the environment
- Target is within ability range and line of sight if required
- Character is not in an action-blocking state (climbing, swimming, carrying a body, or using another ability)

7. Core Rules
- Each character has exactly four active abilities mapped to fixed hotkeys A, S, D, and F.
- The Ability Command Bar updates dynamically when the active character changes.
- Abilities belong to distinct categories: melee takedown, ranged attack, distraction, trap, debuff, disguise, area attack, and companion support.
- No single character possesses abilities from all categories; each covers a distinct tactical niche.
- Some abilities consume limited resources (ammunition, charges) and require pickup or environmental resupply.
- Some abilities have cooldowns that prevent immediate reuse after activation.
- Firearms are campaign-gated and unlock partway through the story for applicable characters.
- Abilities are introduced via in-mission tutorial scrolls that explain their function and controls.
- Ability usage is constrained by character state: disguised characters lose disguise on attacking, climbing vines, or entering water.
- Area-of-effect abilities can harm friendly characters if they are within the blast radius.
- Some abilities are ineffective against specific enemy types (e.g., disguises do not fool samurai; certain distractions are ignored by straw-hat guards).
- Reusable abilities (shuriken, sake bottle, trap) must be retrieved from where they landed before they can be used again.
- Traps placed in enemy vision cones are spotted and avoided; traps in bushes automatically hide the victim's body.
8. BDD Scenarios
Scenario: Silent ranged takedown with reusable projectile
- Given
- a character has a reusable ranged projectile ability
- When
- the player activates the ranged ability and selects the target
- Then
- the enemy dies after a brief animation
- And
- the projectile is in the character's inventory
- And
- a target enemy is within range and line of sight
- And
- the projectile lands at the target's location
- And
- the character must retrieve the projectile before reusing it
Scenario: Luring an enemy into a concealed trap
- Given
- a character has placed a trap in a concealed location (e.g., a bush)
- When
- the player activates a noise-based distraction ability
- Then
- the enemy dies
- And
- the trap is not visible to patrolling enemies
- And
- an enemy enters the trap's trigger zone
- And
- if the trap was in a bush, the body is automatically hidden
Scenario: Disguise infiltration and conversation distraction
- Given
- a character has acquired civilian clothing from the environment
- When
- the player activates the disguise ability
- Then
- the character enters disguised state
- And
- no samurai are in the immediate area
- And
- can walk past regular guards without detection
- And
- can initiate conversations to hold enemy attention, stopping patrols
Scenario: Area crowd-control ability on enemy group
- Given
- a character has an area-of-effect lethal ability
- When
- the player activates the area ability
- Then
- all enemies in the zone die
- And
- a group of non-elite enemies is within the target zone
- And
- no enemies have line of sight to the character during the animation
- And
- the character is vulnerable during the ability animation
Scenario: Firearm unlock at campaign milestone
- Given
- the player has reached the designated campaign mission
- When
- the mission begins
- Then
- applicable characters gain the firearm ability on their F hotkey With limited ammunition (3 shots for standard pistols, 2 for the heavy variant)
- And
- the firearm can one-shot kill most enemies but only stuns heavily armored foes
Scenario: Friendly fire from explosive ability
- Given
- a character throws an explosive area ability
- When
- The described event occurs.
- Then
- the friendly character takes damage or dies
- And
- a friendly character is within the blast radius
- And
- the explosion noise alerts nearby enemies
9. Edge Cases
- Player attempts to use an ability while the character is climbing, swimming, carrying a body, or performing another action
- Ability target dies before the ability completes (e.g., another squad member kills the target first)
- Reusable ability item lands in an unreachable location (shuriken on a roof, sake bottle behind a wall, trap in water)
- Trap is placed in an enemy's vision cone and is spotted before activation, causing enemies to avoid it
- Disguise is broken by environmental interaction (climbing a vine, jumping into water, or being spotted killing a guard)
- Samurai sees through a disguise and attacks immediately, bypassing normal detection buildup
- Friendly fire from area-of-effect abilities kills or stuns squad members (grenades, whirlwind attacks)
- Ability ammunition is exhausted mid-mission with no environmental resupply available
- Shadow Mode queues conflicting abilities on the same target (e.g., two characters attempt to takedown the same guard simultaneously)
- Distraction ability attracts multiple guards at once, overwhelming the player or blocking escape routes
- Character with a disguise attempts to use a hostile ability while in conversation with an enemy
- Noise from an ability alerts guards who were not the intended targets, creating unintended detection chains
10. QA Notes
- Verify all 5 characters have exactly 4 abilities mapped to A/S/D/F
- Verify Ability Command Bar updates correctly within 1 frame of character switch
- Verify cooldown timers display accurately and count down in real time
- Verify ammunition/charge counts decrement on use and prevent use at zero
- Verify reusable items (shuriken, sake bottle, trap) can be retrieved after use and restore the ability
- Verify tutorial scrolls appear at correct campaign milestones and can be re-read from the mission log
- Verify firearm unlock triggers only after the designated campaign mission
- Verify disguises break under all documented conditions (attack, climb, swim, spotted kill)
- Verify area abilities affect both enemies and friendly characters in range
- Verify abilities are unusable while climbing, swimming, carrying a body, or during ability animations
- Verify samurai correctly ignore distractions and see through disguises
- Verify trap placement visibility check works correctly in bushes vs. open ground
- Verify noise radii display correctly as blue circles during targeting
- Verify character-specific health differences (e.g., 6 HP vs. 4 HP) affect survivability during ability animations
11. Mechanic Dependencies
- Stealth Elimination Mechanics (melee takedown abilities are the primary execution method of stealth eliminations; ability system provides the action layer while stealth elimination governs visibility and noise rules)
- Body Manipulation Mechanics (takedown abilities create bodies that must be hidden; carrying capacity differences between characters affect post-ability cleanup options)
- Character Specialization System (abilities express character specialization differences; each character's four abilities define their tactical niche within the squad)
- Character Movement System (ability usage depends on character positioning and movement capabilities; some characters cannot use certain abilities while moving or in restricted terrain)
- Shadow Mode Coordination System (abilities can be queued in Shadow Mode for simultaneous multi-character execution, creating coordinated combos across the squad)
12. UI Links
- Options Menu - Controls settings allow remapping of ability activation keys and shortcuts
- Post-Mission Results Screen - the Heroes tab displays per-character ability usage counts as numbered circular icons next to each character's portrait, showing how frequently each ability was activated during the mission
- Bottom Gameplay HUD Bar - Displays character abilities
- Character Portrait And Selection Panel - The panel controls which character is selected, and the Ability Command Bar displays the abilities produced by this mechanic for the active character.
- Ability Command Bar - The bar displays the four active abilities from the Character Ability System
- Shadow Mode Command UI - The Character Ability System determines which actions are available for queuing in Shadow Mode. Each character's four abilities (displayed on the Ability Command Bar) become the possible queued actions.
- Tutorial Popup Window - Tutorial popups explain newly introduced character abilities such as Hayato's Throwing Stones and Mugen's Sword Wind before the player resumes using those abilities in gameplay.
