New towers would be great!

The Submarine was good, helicopter was great, but what about new towers? Personally a passive tower would be good, one specificity designed for increasing money(without having to pay actual money to increase money outcome) or another long ranged tower. If Ninja Kiwi were to put a suggestion inbox where fellow players could throw ideas into. People would gain interest knowing that their opinions could alter the game.
