New towers

I think it would be cool if you added a new tower that would cost, let's say, 3 mil and it would do enough Area of Effect damage to one shot Phoneix with a cooldown of let's say 10 seconds and the upgrade would cost 10 mil dealing more damage with increased range and reduced cooldown to 5 seconds. The game is super fun and awesome but it's missing some more towers and maybe creatures so I just think that would be super fun.
