Attack of the Johnnies

Johnny has played with the machine not knowing how he had to use it, and now he has made a mess! He has created hundreds of evil clones that want to destroy the lab and steal the protons. You must think carefully where to place the defense towers, each of the towers has a special power that will affect the clones. You can't let them take the protons! If they steal it all, there won't be a way to fix this mess.
