Mr Gunboat is an arcade-style action game developed by Pixel Playbox for Android devices. The game is inspired by retro and arcade games of the past and is designed as a one-finger game. The objective of the game is to defend your position in 'Sector 8' and shoot the asteroids as they fall from the sky.

The game has a simple and fun interface that has an addictive quality of "just one more go." You need to tap to shoot the asteroids and prevent them from hitting the water. If the water levels rise too much, the Earth is doomed, and it's game over. You need to look out for boxes that provide weapons such as rapid fire, laser, triple shot, rainbow shield, and submarine attack. Additionally, you can also find +50% and +100% health that will help you as things get tricky.
