Water TD: a tower defense where the enemy is a flood, and the banks collapse under your towers

In a tower defense, the enemy follows a path. In Water TD, the enemy is the path.

It is a flood. Hundreds of thousands of simulated droplets rushing towards your base, which your towers, planted along the banks, have to stop before they arrive. There are seven towers, and each has two specialisations that change how it fights.

But the real find is erosion. Water eats away at the banks as it flows. Channels widen, islands shrink, and a tower standing on a bank that collapses goes down with it. The terrain changes during the match, before your eyes, because of the enemy. A good spot at the start of a wave can be underwater by the end.

It forces a different way of thinking. You are no longer just looking for the best firing angle, you are looking for ground that will hold. And when the line starts to give, four powers can save the day: fireball, ice wall, lightning, or sending the whole flood back where it came from.

Content is modest but dense: twelve levels, each with its own map and its own flood, and a talent tree of more than 170 upgrades to unlock towers and powers. Twelve levels is not many, and you would like more maps once you understand the system. But the idea is new, and it is well used.

The sight of that water winding, spreading and eating everything does half the work already.

If you find a defense that holds against the last level's flood, share it on the InsertCoins Discord.
