Jump Jet Assault

Your Computer, July 1985

A fairly simple game which owed an obvious debt to Defender. You flew left and right, shooting enemys and attempting to stop technicians being kidnapped..If all the "techs" were lost, the reactor went into meltdown 

   

This was the start of many attempts to write a 'Full Screen Scrolling' game on the Electron. where the complete screen shifted left or right , without you having to wait a week or so. Unlike the BBC Micro, the Electron lacked custom video chips and hardware scrolling,   

Two tricks made it look like the complete screen was scrolling when it wasn't. The game was set at night, leaving the top half of the screen black , in addition the game ran in a window slightly smaller than the full width of the screen, .
