NEXUS – Modular Interaction System (Multiplayer + UI)

Whether you're building an FPS, RPG, survival game, horror experience, or adventure title, NEXUS provides a reusable interaction foundation that scales from simple pickups to complex multiplayer gameplay systems.

Create polished, network-ready interaction systems with fully customizable prompts, highlights, hold interactions, and world-space UI.

NEXUS is a plug-and-play interaction framework built to simplify how players interact with the world. Designed using a modular, interface-driven architecture, NEXUS provides everything needed to create immersive interactions for doors, pickups, buttons, switches, NPCs, objectives, and virtually any interactive gameplay element.

Built with multiplayer as a first-class feature, NEXUS keeps gameplay server authoritative while allowing responsive local UI and visual feedback. The flexible Blueprint component architecture makes it easy to integrate into existing Unreal Engine projects without requiring custom player or character classes.

Gameplay Agnostic

NEXUS provides the interaction framework while allowing you to define your own gameplay logic, making it equally suited for FPS, RPG, horror, survival, adventure, and simulation projects.
