Joz is right. It is from racking up points the extra men come. Like I said before if I beat the score I want it to be because I figured out how the boss works. Obviously Ten figured it out otherwise he wouldn't have had the score for so long.
I am not interested in beating it in a cheesy way legal or not. I did say I didn't like the technique. I tried it just to see if it was possible to beat the score that way.
