Space Invader was one of my first projects with Unity3D where I learned to use the engine by following the Space Shooter Tutorial.
My version includes a whole system increasing replayability. This system adds upgrades, a boss that increases in difficulty the longer you survive the game as well as a local highscore to see who is the best player between you and your friends!
In addition to all those upgrades, I modified the UI, added a start-screen, lifes, a timer and also different kind of weapons!
In 2017 I started changing the project by using the newer UI system. I also moved the highscores to my server. Furthermore I changed a few materials to improve visibility.
