Overview

Fusion Casual MMO is an MMO (Massively Multiplayer Online) game sample with easygoing gameplay, designed for the Fusion Shared Authority topology. Take on the role of a brave knight, armed with your sword and a few abilities, and explore a world full of vicious orcs. To keep the sample scope simple, there are no quests or quest system. However, players can try to find three hidden Golden Chests as an optional objective.
This sample is designed to accommodate 200+ players in the same session. By using Portals, players can be transferred to other sessions while retaining their progress. Additional sessions can be connected to the original, creating an even larger, interconnected world. The game distributes enemy AI calculations among the closest players, allowing for smooth scaling as the number of players increases. Read more in the Distributed Enemy Authority section.
Fusion Shared Authority offers several advantages for MMO games, including simplified scaling with player count and reduced server costs since dedicated servers are not required. However, it also has limitations regarding security and maintainability compared to dedicated servers. This sample includes an example Custom Server Plugin that validates and controls important game logic such as damage, movement and object spawning. The plugin demonstrates how to add a layer of server-side control to a Fusion Shared Authority game for enhanced security. Using the custom plugin is completely optional. Dedicated servers are still a great option, especially for more serious MMO games targeting PCs and consoles, see Choose a Topology.
