For the sound effects I used sfxr again. The explosion sound effect I found on the web. It's a public domain sound effect so we can use it in Droid Invaders. The music I recorded myself. With real instruments. Yes, I'm that old-school. Here's the list of audio files of Droid Invaders.
■ click.ogg, a click sound used for the menu items/buttons
■ explosion.ogg, an explosion
■ music.mp3, the rock/metal song I wrote for Droid Invaders
