I, all of a sudden, on the first level with armored units, I came into possession of 173 upgrade points. I then noticed that my "Nailer" killed armored tanks in 3 hits.
In addition to discoking99's, I found some that I think work too: NOP = Slime in your face, QWH = Popcorn?, AWVMOP = Big, QY = Hyperspace (Somewhat like KQ).
