Objective: Survive 11 waves
I had to break my own rule to complete this level on hard. Normally I would always say that the most effective way of completing levels is to upgrade your towers before building others, when I tried this method, I failed.
The level can be completed by building three un-upgraded towers. It will take you to around wave 5 or 6 before you can build your second splash tower. If you are going to take out the pink blobs, then make sure that this doesn’t come above eliminating the enemies.
