Well, I've got both Gradius Galaxies and Konami's Arcade Advanced games for GBA. During the opening of Gradius Galaxies, there is a Gradius timeline that shows Scramble, and then Gradius, and then Salamandar, and then the rest of the Gradius games.
Well, I know that Salamander/Lifeforce was a spin-off of the series, but how is Scramble related to the line? I've played quite a bit out of it on the Arcade Advanced cart and it doesn't really scream Vic Viper to me.
:P
