Anyone got any tips for Sinking Atlantis?

I just can't get past it, even using the recommended towers

No idea, im also stuck there - did it nearly, but the towers, that are proposed by the game are complete crap for the map.
I think the 4th campaign is not enjoyable at all

theres certain key areas you want to put all your towers at depending on which wave set, goes like 1 chokepoint, 2, 2, and then 3. find the spots where they intersect and build around it, spreading out is a no no.

I think i did 1 big choke point at the center north where 3 converge and 1 chokepoint at the bottom 2 lanes coverging

I actually completed it yesterday before you commented but thanks for the advice anyway!
