Space Battle Live Wallpaper is a free Android app developed by Lyrie that brings retro action to your home screen. The app offers a lost genre of games that includes Galaga, Space Invaders, and Atlantis. You can tap on enemy ships to destroy them or tap on the screen to fire the hero ship's weapons. Moreover, you can touch the hero ship to shoot the monstrous Super Laser.

The app has a full settings screen where you can customize preferences for visual theme, weapon types, weapon randomization, camera behavior, score display, tilt controls, and more. It works well as either a live wallpaper or a Daydream on 4.2+ devices. The app is available for free on the Google Play Store and offers a unique way to personalize your device with retro action.
