GAS Combat Architecture
I built a four-skill QWER ability set with the Gameplay Ability System. Gameplay effects, cooldowns, tags, attributes, and cues handled state and feedback.

Sunset Hollow Gameplay Reel
Overview
Sunset Hollow is the portfolio's Unreal/C++ systems proof. It shows gameplay architecture beyond Unity, including GAS-based combat, AI behavior, navigation customization, designer-facing Blueprint exposure, and object lifetime management across decoupled systems.
My Role
I architected and implemented the core gameplay systems: player abilities, enemy abilities, health and cooldown state, AI behavior, custom navigation interaction, and C++ systems exposed to Blueprint for faster iteration.
Key Systems
Enemy AI
I implemented Behavior Trees with 360-degree sight perception, patrol behavior, chase states, interruptible attacks, and randomized ability casting so enemies could shift behavior based on player proximity and combat state.
Custom Navigation
I engineered a custom jump/navigation interaction to replace default Nav Link Proxy behavior for mesh-to-mesh traversal, giving the project more control over how movement events were triggered and resolved.
Combat System and Dash Ability
I developed a three-hit combo for basic attacks and a dash ability with invulnerability frames, cooldowns, and movement state so the player could engage in fast-paced combat with responsive feedback.
Outcome
Sunset Hollow broadens the portfolio beyond Unity VR. It shows that I can work directly in Unreal C++, build on engine-level gameplay frameworks, and create maintainable systems that remain usable from designer-facing tools.
