A full, ready-to-use stealth gameplay toolkit for Unreal Engine 5 — free.
Build believable stealth experiences quickly: AI perception (sight/hearing/touch), patrols on splines, hide-in-grass mechanics, throwable noise items with a custom throw widget, stealth takedowns with a target widget, player crouch + IK fixes, health bar UI, and polished alert logic.
Everything is implemented in Blueprints only, includes demo maps, animations, materials, and is ready to plug into your project.
