How to Install & Use GAS in Unreal Engine 5 (Single Player Focus) | UE5 Ability System Tutorial

In this Unreal Engine 5 tutorial, we dive into the *Gameplay Ability System (GAS)* and walk through how to *install it, set it up, and start building abilities* — but with a twist:
💡 We focus entirely on **single-player games**, making the workflow far simpler and easier to understand than the usual multiplayer-heavy tutorials.

If you've been wanting to use GAS without dealing with multiplayer replication, this is the perfect beginner-friendly starting point.
