I just got my Embryon up and running, and am wondering what the best way to play it is. From the few games I've played, it seems like bonus is a big part of the score, like many Bally games of this era. My rule card is missing, so what's a good way to rack up some bonus and a multiplier? Is multiball worth going for? I'd love to hear any commentary anyone may have on how to play Embryon well.
