Tower Defense : Fish Attack

Tower Defense: Fish Attack takes the usual invading horde and swaps it for something stranger - an army of fish, whales, jellyfish and turtles marching in from the water. The threat is still a straight line problem: pick where towers go, cover the paths the creatures take, and make sure nothing slips through with your defenses still reloading. Because the game runs in portrait, the lanes tend to be narrow and vertical, which rewards towers that hit hard in a small space over ones that spread damage wide.

Waves climb steadily in size and speed, and the game keeps running as long as you can hold the line, so the real target is not a fixed level but how many waves you can survive before the sea finally gets through. Placement early on matters more than upgrades late, since a gap left open in wave three becomes a much bigger problem by wave twenty.

How to play

Build towers along the shoreline where the fish, whales and jellyfish will pass, aiming to cover every lane they can take. Survive as many waves as you can - each one arrives larger and faster than the last, so towers that stop early waves cleanly matter more than ones you add in a panic later. Reposition or add towers between waves if a gap in your coverage starts letting creatures through.

Controls

Tap or click a location to place a tower, and tap or click existing towers to upgrade them. No other controls are needed - the creatures move and attack automatically once a wave begins.
