It's not often I say this but I think I may have found a rather decent Android clone in Chrawfish Interactive's Arcade Shoot em up ' Scrambler ', which is a clone of the 1980's Arcade title Scramble ; a game originally developed by Konami and distributed in North America by Stern Electronics. For those of you who have never played this game before all those years ago, it was a classic early horizontal shoot-em-up where you had to blow up ground targets and missiles with bombs or bullets and navigate increasingly difficult terrain. It was so popular, it spawned many home computer conversions!
