Objective: Survive 26 waves
To complete this level on hard you should start by fully upgrading the scout tower which is built as you start.
Laser towers cannot harm the pink blobs. But they can target them an fire at them as if they were able to cause harm. This level can be completed on hard by using this principle. You’ll need to make room for two laser towers by building a scout tower and destroying the blob in the middle of the block, then the blob to the middle right.
Make sure you then SELL this scout tower, otherwise you’ll destroy the pink blob which you need for the laser towers to target.
Build your laser tower and target the blob to the left. I will not harm the blob but will rapidly send fire power down the centre line.
Build another laser tower behind the first. This second laser tower will target the blob.
When you can, upgrade the laser towers.
A splash tower here will help eliminate any enemies that might otherwise get through.
Upgrade the splash tower.
Build slow towers to slow the enemies down so that the laser towers will be able to shoot them more frequently.
Upgrade the slow towers with the spare resources which you have.
