Boat Invasion

Pressure rises along the harbor walls. In the waters of Boat Invasion, the city stands behind its gates as attack craft push in from the sea. Land plots line the shoreline, giving room for defense towers aimed at targets moving across the water. Six attack tower types cover the offensive side. Two support towers add extra help to the line. Four maps hold 50 enemy waves each. Early assaults send weaker boats forward. Larger ships appear near the end, and boss vessels enter the route with much heavier durability.

How to play?

Place towers on the available ground beside the water route, then spend money on upgrades that raise damage output and extend firing distance. Incoming vessels carry different health values, which makes tower stats and placement important during each wave. Money also covers improvements for every structure on the shore. If a ship reaches the city gates, the defense fails immediately.
