Area-of-Effect Crowd Control Attack

Advanced

Shadow Tactics: Blades of the Shogun

Status: Released
Year: 2016
Genre: Indie, Strategy
Platforms: Windows, macOS, Linux

1. Summary

An area-of-effect melee crowd-control attack lets its owner dash to a designated target zone and perform rapid cuts, killing non-Samurai enemies inside the radius in one committed action. In Shadow Tactics this is represented by Mugen's Sword Wind/Kazakiri on the S ability slot: it is highly effective against clustered guards, but takes several seconds, leaves the attacker vulnerable during execution, excludes Samurai, and is limited by a long cooldown.

3. Design Intent / Job Story

When multiple non-Samurai enemies are clustered tightly enough to block a route, I want to commit one high-impact area attack against the group, so that I can collapse the encounter quickly while accepting the risk of exposure, cooldown, and elite-enemy immunity.

4. Role in Gameplay Loop

Provides a high-impact answer to dense non-Samurai guard clusters that are too risky or slow to dismantle one by one
Converts positioning and enemy grouping into a lethal payoff after lures, patrol timing, or route planning
Creates a deliberate risk-reward choice because the attacker must enter the target zone and remains vulnerable during the animation
Reinforces enemy hierarchy by explicitly failing against Samurai, preserving the need for specialized anti-Samurai methods
Adds cooldown pressure so players reserve the attack for meaningful multi-target opportunities instead of using it as a default takedown

5. Preconditions

Mission is in active gameplay and the ability owner is selectable, alive, and controllable
The area attack ability is unlocked and visible on the selected character's ability bar
The ability is off cooldown
A valid ground target point can be selected within ability range
At least one enemy is inside the intended area of effect for the attack to have tactical value
Targets intended to die are non-Samurai enemies
The attacker can path or dash to the selected center point
No enemy should be able to shoot or otherwise punish the attacker during the execution window if the player wants a safe use

6. Parameters

Parameter	Value	Type	Notes
Ability slot	S	input binding	Observed/default PC slot used for Sword Wind/Kazakiri.
Targeting mode	Ground point / area circle	enum	Player chooses a target position rather than selecting one enemy.
Target preview	Red circle	visual	Tutorial frame shows the kill zone as a red area circle.
Execution movement	Dash/rush to center	action	The attacker moves to the center of the chosen area before killing.
Valid targets	Non-Samurai enemies	enemy filter	Enemies inside the area that are not Samurai are killed.
Samurai effect	No effect / no kill	enemy-state result	Samurai are explicitly immune to this area attack.
Demonstrated max kills	Up to 3	integer	Source evidence describes and shows three enemies killed in one use.
Execution duration	Several seconds / TBD exact value	duration	The attack takes a few seconds and leaves the attacker vulnerable.
Cooldown	Long / TBD exact value	duration	Long cooldown prevents repeated use.
Safety requirement	No enemy line of sight/fire	tactical condition	Use is safest when no enemy can see and shoot the attacker during the animation.

7. Core Rules

The player activates the area attack from the selected character's S ability slot in the observed/default PC layout.
Activation enters a target-selection state where the player chooses a ground position rather than a single enemy.
The targeting preview communicates the affected area as a red circle.
On confirmation, the attacker dashes or rushes to the center of the selected area.
During execution, the attacker performs a rapid multi-cut melee sequence rather than separate player-issued attacks.
All valid non-Samurai enemies inside the area are killed by the sequence.
Samurai inside the area are not killed by this attack and must be handled by Samurai-valid counters.
The attack is intended for clustered groups and can eliminate up to three enemies in documented gameplay/tutorial evidence.
The execution takes several seconds, during which the attacker is vulnerable to enemy fire or other punishment.
Safe use requires checking sightlines and ranged threats before committing to the animation.
After execution, the ability enters a long cooldown that prevents immediate reuse.
The attack's high lethality must not bypass alarm, body, or visibility consequences caused by nearby witnesses outside the affected group.

8. BDD Scenarios

Scenario: Kill clustered non-Samurai enemies

Given: the area attack ability is ready
When: the player activates the S ability slot and confirms the target point
Then: the attacker dashes to the center of the circle
And: three non-Samurai enemies are clustered inside the targeting circle
And: the attacker can reach the selected center point
And: the rapid-cut sequence kills the enemies inside the area
And: the ability enters its long cooldown

Scenario: Samurai survives inside the area

Given: the area attack ability is ready
When: the player executes the area attack
Then: the non-Samurai enemies inside the area are killed
And: a Samurai stands inside the targeting circle with one or more non-Samurai enemies
And: the Samurai survives because this attack has no effect on Samurai

Scenario: Unsafe use under enemy fire

Given: the area attack ability is ready
When: the player commits the area attack
Then: the attacker remains vulnerable while the sequence completes
And: ranged enemies can see the attacker during the execution path or animation
And: visible enemies can punish the attacker before control fully returns

Scenario: Cooldown blocks repeated use

Given: the player has just executed the area attack
When: the player attempts to activate the same ability again before cooldown recovery
Then: the ability does not execute
And: the Ability Command Bar communicates the unavailable cooldown state

9. Edge Cases

Target circle contains a mix of Samurai and non-Samurai enemies; only valid non-Samurai targets die
An enemy exits the circle or is moved by patrol timing between targeting and execution
The selected center point is blocked, unreachable, or becomes invalid before the dash resolves
A witness outside the area sees the attack or body aftermath and triggers alarm consequences
A ranged enemy outside the area has line of sight and can shoot the attacker during the vulnerable animation
The ability is queued or attempted while already on cooldown
The target group is too spread out, causing only part of the patrol to be hit
The attack kills the target group but leaves bodies in visible positions that create later discovery risk
The player attempts to use the attack as an anti-Samurai solution and receives no kill on the Samurai
The attacker is interrupted, killed, or otherwise punished before the committed sequence completes

10. QA Notes

Verify S-slot activation enters ground-targeting mode and displays the red area circle
Verify confirming a valid point makes the attacker dash to the center of the circle before executing cuts
Verify all non-Samurai enemies inside the radius die when the sequence resolves
Verify Samurai inside the radius survive and remain governed by Samurai immunity/counter rules
Verify clustered three-enemy tutorial setup can be cleared in one use
Verify the attacker is damageable or otherwise vulnerable during the several-second execution animation
Verify visible ranged enemies can punish unsafe uses while enemies without line of sight do not
Verify the ability enters a long cooldown after execution and cannot be reused until recovery
Verify cooldown/unavailable state is reflected in the Ability Command Bar
Verify bodies, witnesses, and alarms behave consistently after the attack rather than being suppressed by the ability

11. Mechanic Dependencies

Stealth Detection System (Stealth detection and line-of-sight rules determine whether the attacker is safely hidden or exposed during the vulnerable animation.)
Character Ability System (This is a specialized active ability within the Character Ability System and uses its readiness, targeting, cooldown, and character-state rules.)
Enemy Type Hierarchy (Enemy type hierarchy determines valid targets, because this attack kills non-Samurai enemies but must respect Samurai immunity.)
Shadow Mode Coordination System (Shadow Mode can coordinate timing, distractions, or simultaneous actions around this committed area attack.)
Samurai (Samurai are the explicit exception to this mechanic, surviving inside the area and requiring separate Samurai-valid counters.)
Four-Slot Ability Binding Framework (The Four-Slot Ability Binding Framework exposes the attack through the selected character's S ability slot and its availability state.)

12. UI Links

Bottom Gameplay HUD Bar - The Bottom Gameplay HUD Bar contains the ability bar and active character context needed to select the owner and execute the attack during missions.
Ability Command Bar - The Ability Command Bar exposes the S-slot Sword Wind command, shows targeting and availability, and communicates cooldown/unavailable state after use.
Shadow Mode Command UI - Shadow Mode Command UI can be used to plan coordinated timing around this high-commitment area attack alongside other character actions.
Enemy Vision Cones - Enemy Vision Cones inform the safe-use decision because the attacker is vulnerable if enemies can see and shoot during the committed animation.
Tutorial Popup Window - The Tutorial Popup Window introduces Sword Wind with text and visuals explaining the red circle, dash-to-center behavior, kill radius, and long cooldown.
