I Made Among Us in One Day with Unity ?

I created many of the basic game mechanics of the game Among us in less than 24 hours with Unity. This is the first video of our tutorial series on how to create the viral video game Among Us. We will show you how to create your own version of Among Us. We will go through the game mechanics and create Among us from the ground up.

This series on how to create Among us in Unity will be one of the complete and extensive game series we have done so far. We will teach you how to create the game, the chat system, and multiplayer gameplay with Photon PUN 2.
