 ## Exploring the project
-BossRoom is an 8-player co-op RPG game experience, where players collaborate to take down some minions, and then a boss. Players can select between classes that each have skills with didactically interesting networking characteristics. Control model is click-to-move, with skills triggered by mouse button or hotkey.

 The game is server-authoritative, with latency-masking animations. Position updates are done through NetworkedVars that sync position, rotation and movement speed. NetworkedVars and Remote Procedure Calls (RPC) endpoints are isolated in a class that is shared between the server and client specialized logic components. All game logic runs in FixedUpdate at 30 Hz, matching our network update rate.
