Scramble was released in February 1981 in Japan.
Sometimes unfairly referred to as a 'poor man's Defender', Scramble was not only the world's first multi-level shoot-em-up, it was also the first of its type to feature a re-fueling system. These innovations helped to ensure that Scramble was a well deserved commercial success for Konami.
This game was the first title to use the 'Scramble Hardware', which was later used for "Super Cobra
", "Lost Tomb
", "The End
" and a number of other titles. Many of these titles were actually bootlegs of other games, such as Namco's "Pac-Man
". This was because Konami neglected to give Scramble ANY copy protection whatsoever; making it incredibly easy to run just about anything that used a Z80 processor, which, at the time, was pretty much every game out there. There were, of course, a lot of Bootleg copies of Scramble itself floating around, such as "Explorer
" or "Strafe Bomb
Scramble is considered the first in the "Gradius
" series according to the Nintendo Game Boy Advance "Gradius Galaxies" intro sequence.
This game had a Bulgarian bootleg called "Memory Devices Facility".
A Scramble unit appears in the 1983 movie 'Joysticks'.
