Multiplayer Online Sessions

Multiplayer Online Sessions is an Unreal Engine plugin that provides Steam-backed online session functionality, allowing players to host, find, join, and leave matches over the internet.

I created a custom Online Subsystem derived from Unreal Engine’s Online Subsystem and configured it for Steam.

Session Flow

• Created custom functions built on the session interface, designed to be called by menu actions such as Host and Join.
• Implemented custom delegate objects for session setup, match discovery, joining, and leaving.
