This project, technically speaking, is a big step up from Snake. We will learn how to handle multiple different alien types with unique behaviour, appearance and properties. Other features of the game include rapid fire lasers, scrolling background, persistent high score and a cool star-burst particle system explosion effect.

In this project we are introduced to Java and game programming patterns which are key to writing complex games with manageable code. We will learn about and use the Entity-Component pattern, Strategy pattern, Factory pattern and Observer pattern.

The techniques learned in this project are vital if you want to design your own games while structuring your Java code in a way that allows your games to become more complex and yet keep the code manageable.
