Mission Objective Variety — Shadow Tactics: Blades of the Shogun

1. Summary

The mission objective system defines a diverse palette of primary goal types that structure the campaign's discrete levels. Each mission assigns one or more core objectives — assassination, rescue, infiltration, theft, eavesdropping, kidnapping, escort, or sabotage — and pairs them with a curated character roster and unique environmental conditions. This variety forces the player to recombine stealth, combat, and coordination mechanics in novel ways across every level, while a layered badge system adds optional completionist constraints on top of the primary goal.

3. Design Intent / Job Story

When I begin a new mission, I want the primary goal and available squad to differ from the previous level, so that I am forced to rethink my tactics rather than repeat the same approach.

4. Role in Gameplay Loop

Defines the win condition for each discrete level in the campaign
Drives character selection and ability relevance by curating which heroes are available per mission
Creates pacing variety across the campaign by alternating between lethal and non-lethal primary goals
Provides the foundation on which the Mission Badge System layers optional challenge constraints
Governs environmental special-rules (snow footprints, night visibility, torch mechanics) that modify the stealth loop for specific missions

5. Preconditions

Player has selected and loaded a mission from the campaign or mission select screen
The mission's designated character roster has been initialized and spawned at level start
Mission-specific environmental states (weather, time of day, terrain hazards) have been applied
Primary objective targets and interactables have been placed according to the level layout

Difficulty levels	normal, hard	enum	Hard difficulty required for one badge per mission

7. Core Rules

Every mission in the campaign has exactly one primary objective type that defines victory conditions for that level.
Each mission assigns a curated subset of the playable character roster; the player cannot use characters not designated for that mission.
Later campaign missions may unlock the full five-character roster, while earlier missions restrict the squad to two or three heroes.
Primary objective types include: Assassination (eliminate a named target), Rescue (free an ally or civilian from captivity), Infiltration (reach a target zone undetected), Theft (steal documents or items), Eavesdropping (overhear specific conversations), Kidnapping (abduct a target alive), Escort (guide a character to an extraction point), and Sabotage (destroy objects or mark cargo).
Some missions combine a primary objective with secondary mandatory tasks that must be completed in sequence.
A subset of missions alter base stealth rules through environmental modifiers: snow leaves visible footprints, darkness reduces enemy sight range but torches extend it, and conspicuous surfaces make noise.
Mission failure occurs if the player character is killed, if a mandatory escort target dies, or if a mission-specific failure condition is triggered.
Missions can be replayed from a mission-select screen after their first completion.
Mission completion time is tracked internally and displayed when the player opens the pause menu.
Primary objective completion immediately ends the mission and transitions to the post-mission results screen.

8. BDD Scenarios

Scenario: Assassination objective completion

Given: the player has loaded a mission with an assassination primary objective
When: the player eliminates the target using any valid takedown method
Then: the mission ends immediately
And: the named target is alive and patrolling the level
And: the Post-Mission Results screen is displayed

Scenario: Rescue objective with escort requirement

Given: the player has loaded a mission with a rescue primary objective
When: the player unlocks the cell and the ally joins the squad
Then: the player must guide the ally to the designated extraction zone
And: the captive ally is locked in a cell
And: the mission completes only when the ally reaches the extraction point

Scenario: Eavesdropping objective

Given: the player has loaded a mission with an eavesdropping primary objective
When: the player moves a character within listening range without being detected
Then: the conversation audio plays and the objective marks as complete
And: the target conversation is occurring in a patrolled area

Scenario: Theft objective with item retrieval

Given: the player has loaded a mission with a theft primary objective
When: the player picks up the item with any character
Then: the item is added to the squad inventory
And: the target item is in a guarded location
And: the mission completes when the squad reaches the extraction point with the item

Scenario: Environmental modifier alters stealth approach

Given: the player has loaded a snow mission
When: a character walks across the snow
Then: visible footprints are left behind
And: the ground is covered in snow
And: enemy guards who spot the footprints will follow the trail to investigate

Scenario: Mission failure on escort target death

Given: the player has loaded a mission with a kidnapping or escort objective
When: the target NPC is killed by an enemy or environmental hazard
Then: the mission fails immediately
And: the target NPC is following the squad
And: the Mission Failed screen is displayed

9. Edge Cases

Player completes the primary objective while an alarm is active; the mission still succeeds if the target condition is met
Player kills a mission-critical NPC who is not the assassination target, failing a rescue or escort variant of the mission
Environmental modifier (snow footprints) leads guards to the player's hiding spot after the objective is already complete but before extraction
Player uses a disguise to walk past guards carrying a stolen objective item; the disguise is broken by the item's visibility
Multi-area missions lock the squad into a new zone after a story trigger, preventing backtracking to complete missed badges
Player triggers a mission failure condition after the primary objective is complete but during the extraction phase
Speedrun timer continues counting during pause menu inspection; pausing the game does not stop the internal timer
Player reloads a save from before the primary objective was completed after already earning badges; badges persist but the player must re-complete the objective
Mutually exclusive mission paths (e.g., unlock north door vs. south door) require multiple playthroughs to earn all badges
Character-specific objective steps fail if the required character is killed before completing their part of the task

10. QA Notes

Verify each of the 13 base campaign missions has a clearly defined primary objective type
Verify the assigned character roster matches the mission design and no unauthorized characters are selectable
Verify mission completion triggers correctly for each objective type (assassination, rescue, theft, eavesdropping, kidnapping, escort, sabotage)
Verify mission failure triggers when escort/kidnap targets die or when mission-specific failure conditions are met
Verify environmental modifiers (snow, darkness, torches) apply only to designated missions and affect AI behavior as specified
Verify the in-mission timer displays correctly in the pause menu and counts real elapsed time
Verify replaying a mission from mission select preserves previously earned badges and reveals hidden badge conditions
Verify multi-zone missions correctly transition between areas and lock/unlock terrain as designed
Verify that killing a named target in a non-assassination mission fails the mission if that NPC was required for a rescue or escort objective
Verify post-mission results screen accurately reflects completion status, time, and earned badges

11. Mechanic Dependencies

Stealth Detection System (stealth detection rules are modified by mission environmental states (night visibility, torch radius, snow noise))
Character Ability System (the curated character roster per mission determines which abilities are available to solve the objective; ability tutorials are gated by mission progression)
Stealth Elimination Mechanics (elimination mechanics are the primary tool for assassination objectives and for clearing paths to other objective types)
Mission Badge System (each mission's 9 badges layer optional constraints on top of the primary objective; badge conditions reference mission-specific targets and restrictions)
Environmental Interaction System (environmental interactions (snow footprints, torches, destructible objects) are mission-specific modifiers that change how objectives must be approached)
Alarm Response System (alarm response triggers when stealth is broken during any objective, altering patrol density and potentially making the objective harder or impossible)
Character Movement System (movement capabilities (climbing, swimming, hookshot) gate which paths and areas are viable for a given mission's objective)
Enemy Type Hierarchy (enemy type composition varies per mission and dictates which tactics are viable for the assigned objective)
Shadow Mode Coordination System (Shadow Mode coordination is required for complex multi-character objective executions (e.g., simultaneous takedowns to reach an assassination target))
