Blueprint Squad-Based Tactical JRPG Framework (Powered by GAS)Technical Overview
This package is a production-ready, highly extensible Tactical JRPG Framework built entirely on the Unreal Engine 5.7 Gameplay Ability System (GAS). Designed as a Blueprint-first solution backed by a modular plugin architecture, it enables developers to leverage the full power of GAS without requiring native C++ programming.
Inspired by large-scale squad-based tactical combat systems similar to The Last Remnant, the framework focuses on formation-driven combat, strategic AI decision-making, and scalable multiplayer-ready architecture.
Built for both single-player and multiplayer projects, the framework emphasizes flexibility, performance, and long-term extensibility for commercial production pipelines.
Core Technical Architecture📑 Fully Data-Driven WorkflowUnified Data Management
All gameplay data — including character stats, equipment, skills, formations, and stage modifiers — is managed through centralized Data Tables and optimized Data Registries for efficient asynchronous asset loading and memory management.
Scalable Pipeline Design
The framework is fully aligned with Unreal Engine’s Asset Registry ecosystem, enabling seamless future expansion into native C++ systems and Primary Data Assets without restructuring existing content.
🛡️ Production-Ready GAS IntegrationAdvanced Gameplay Attributes & Effects
Includes pre-configured GAS Attribute Sets for both individual characters and entire Squads (Unions), allowing buffs, debuffs, morale systems, and damage calculations to dynamically scale across formations.
Animation-Driven Ability Execution
Gameplay Abilities are tightly integrated with AnimMontages and Gameplay Cue Notify workflows, enabling precise timing windows for attacks, counters, reactions, and synchronized combat events.
Modular Gameplay Tag Architecture
Extensive Gameplay Tag support allows clean management of combat states, AI behaviors, formation logic, targeting conditions, and status effects in a fully scalable manner.
☫ Advanced Squad Formation & Union LogicDynamic Formation Alignment
High-performance formation algorithms automatically calculate battlefield spacing, orientation, and positioning for grid-based or free-form squad deployments.
Tactical Command Evaluation System
A context-sensitive combat evaluation engine dynamically generates strategic command options based on battlefield conditions such as:
Morale
Flanking
Interception
Squad Status
Formation Advantage
Threat Prioritization
This creates highly varied and replayable combat encounters with adaptive tactical decision-making.
Squad Management UI
Includes ready-to-use CommonUI templates for:
Team Management
Squad Editing
Formation Configuration
Leader Assignment
Turn Order Display
All UI systems are designed for easy extension and platform scalability.
🌐 Server-Authoritative Multiplayer ArchitectureMultiplayer Session Integration
Fully integrated with Unreal Engine’s multiplayer session framework, supporting:
Matchmaking
Lobby Systems
Listen Servers
Dedicated Servers
Seamless Session Joining
The architecture is designed to support both cooperative and competitive tactical gameplay environments.
Replicated Turn-Based Combat State Machine
Combat states, turn orders, timers, formation updates, and gameplay events are fully replicated using a server-authoritative model to ensure deterministic combat synchronization across all connected clients.
Optimized Network Replication
Strategic AI decisions, command packets, and squad state updates are replicated efficiently through optimized Server RPC workflows and controlled Net Update Frequency strategies to minimize bandwidth overhead.
🎯 Concurrent Movement & Dynamic Interception SystemsSimultaneous Squad Movement
Supports concurrent squad movement where multiple formations advance toward objectives or targets simultaneously without blocking the game thread, enabling large-scale battlefield flow and real-time tactical transitions.
8-Way Flanking & Tactical Positioning
Advanced directional evaluation systems automatically detect:
Flanking Attacks
Rear Assaults
Cross Engagements
Deadlocks
Positional Advantages
using 8-direction battlefield vector analysis.
Real-Time Interception Events
When opposing squads collide during movement phases, the framework automatically triggers interception events that dynamically:
Recalculate combat targets
Interrupt movement states
Re-evaluate AI strategies
Trigger contextual Gameplay Abilities
Update formation behavior in real time through GAS
This allows battles to evolve organically based on battlefield positioning and tactical movement.
