Steredenn — our game — is available on PC/Mac/Linux and Xbox One!

Creating a 2D game with Unity

Using the Unity native 2D tools, you will learn how to make a small “Shoot’Em Up” (abbreviated to shmup thereafter) with this tutorial.

The result will be a lot like this demo:

With time and work you can make a game like Steredenn. We actually use the code of the tutorial in our game!

We will focus on a shmup with an horizontal scrolling. However, if this tutorial does its job correctly, you’ll understand how to extend the code to many other genres.

The assets, gameplay and original idea come from the game The Great Paper Adventure. Damien created this game a few years ago using XNA. When we started this tutorial, we thought it was a perfect material to explain Unity.


Unity3D is a popular and complete solution to create multiplatform video games. This tutorial assumes that you are at least a bit familiar with a programming language. Knowing the tools and the engine is a plus, but is not necessary.

This tutorial is made with the Unity 5 Personal Edition (free) version.

If you’d rather watch this tutorial than read it, then have a look at Jay Jennings’s work from Game Dev Nation.
