Sky Fighter - A SMS Shoot em up dump is the first version available on the internet
Even more retro goodness from our friends SMS Power is the recently internet released 'Sky Fighter' for the Sega Master System. This game by Clover Soft 1990 is a top scrolling shoot em up that according to SMS Power, was first discussed in HG101 article on Clover Soft, showing a single screen from an advertisement. It was apparently released on both MSX and SMS, but up to this day the MSX version hasn't surfaced. This SMS dump of the game is the first version available on the internet.
It's not often I say this but for what looks like a good shoot em up, Sky Fighter isn't. The game has its usual shoot em up charm with enemies to blast and power ups to pick up, but the ground based scrolling is very jerky and the soundtrack playing is one of the worst I've ever come across. Pretty much as soon as the game starts your ears will be hurting as it sounds bloody awful. Still if you can look past those, you might actually enjoy this game... Good luck!
