This tutorial series shows the entire process of creating a fully featured, polished, 2D game in Unity 4.5! We show many of Unity's new 2D features, such as the sprite renderer and editor - as well as animation, sound, custom character controllers, and more! At the end of the series, we wrap up by constructing two fully featured levels for our game.
This series expects a beginner-level understanding of C# as well as a very basic understanding of Unity's interface. However, people completely new to Unity can use this series as an accelerated introduction to the beginner to intermediate features of the engine.
