Cannon Master is an exciting arcade game that requires you to defeat monsters by creating missiles. The game is developed by RETRO BOX and available on Android for free. The gameplay is simple yet challenging, as you need to upgrade your main cannon, add sub cannons, collect items, and create a powerful option cannon to defeat boss monsters within the time limit.

One of the unique features of the game is the sub cannons that attack enemies in the sky automatically, each with its own characteristics. You can make good use of their features to create a strategic advantage. As you defeat monsters, you earn gold to upgrade your main cannon and missiles. The items collected throughout the game also help you have special abilities and level up their effects.
