Getting Started

In the further course of this documentation and especially in network-related chapters, you will find additional window tabs for Netcode. These are specifically directed at implementation details of the networking solution.

I'm a Unity Netcode tab!

Playing the Game

Open the Intro scene, and press the Play button! It throws the player directly the Lobby scene, where when using the Online mode (default), they are already connected and authenticated with Unity Gaming Services.

Host a game, ready up and start the game. Since it is a bit boring to play alone, make your lobby public or join it via the displayed join code in a second build!

Overview of Network approaches

For quick access, you can find a list of different network approaches used for a specific aspect or demonstration purposes in the table below.


If you are unexperienced with networking or trying to get familiar with the asset in general, I would recommend not using the direct links below, but going over the sections in the sidebar from top to bottom one by one.

  • players can place towers everywhere
  • players can help defend each other
  • units spawn on all paths


  • one defense point per player
