Cannon Shot 3D is a strategy game where players take on the role of an artillery officer in charge of defending a coastal fortress from enemy ships. The objective is to accurately destroy incoming vessels by firing cannons at the correct angles and trajectories, taking into account factors such as wind direction and bullet speed.
To play, players use their mouse to aim and fire cannons at the enemy ships. The game tracks the trajectory of the cannonballs, showing how they will hit the water or the ship, allowing players to adjust their aim. The player must balance the risk of damaging nearby friendly ships with the need to destroy the enemy vessels.
Players must make split-second decisions to maximize their chances of success, as the enemy ships can catch fire and sink, removing them from the battlefield. The game runs in the browser without the need for downloads or registration, making it easy to play anywhere.
