Hold the Coast Against Enemy Ships
Boat Invasion is a tower defense game where enemy boats travel along the water toward your town. You do not control a soldier or steer a ship yourself. Your job is to build defensive towers in good positions and stop every enemy vessel before it reaches the town gates. Each boat that gets through costs you lives, so a weak point in your defense can quickly become a serious problem.
The game uses the mouse for its main controls. You select a tower and place it on an available spot beside the water. Once built, the tower attacks enemy boats automatically when they enter its range. This means the most important decisions happen before and during each wave. A tower placed in a poor location may get only a few chances to fire. A well-placed one can attack several boats as they move along the route.
Destroying enemies gives you money that can go back into your defenses. You can spend it on additional towers or improve structures that are already helping you.
Different Towers Have Different Jobs
Boat Invasion includes six types of attacking towers. The available weapons range from basic gun defenses to stronger equipment such as missile turrets. Using several tower types gives you more options as tougher ships start entering the battle.
The game also has two support tower types. These do not simply fire another weapon at the boats. One can improve the attack range of nearby defenses. Another can increase their firepower. Correct placement makes these support structures useful because one tower can help several attacking defenses around it.
This creates an important choice. You could spend your money on another weapon tower, or use a support structure to make several existing towers stronger.
Spend Your Money Carefully
Building everything as soon as you can is not always the safest plan. New boats keep arriving, and stronger defenses cost money. Players need to watch how their current towers perform before deciding what to buy next.
A section where boats take little damage may need a new tower. Another area may already contain several weapons and benefit more from an upgrade or support tower.
The enemy route also matters. Areas where ships remain in range for longer periods can make excellent positions for strong defenses.
Boat Invasion keeps the controls simple while giving players plenty of choices. You build, watch the next group of ships approach, earn money from destroyed enemies, and strengthen the shoreline before the next threat reaches the gates.
