Side Arms: Hyper Dyne

'It's the 21st century, and somewhere between the stars and Earth a battle rages.

Streaking across the sky, the stars themselves are clashing with bizarre creatures from deep space who have Earth as their ultimate target. Massive alien hordes are descending to invade your home base.

If you can meet the challenge, you will command the brightest stars ALPHA and BETA in a space race like none before. You must intercept the aliens and shoot first or forget about later. Your star force sweeps the heavens loaded with secret advanced weaponry and protective armor. Snake-like creatures flash out from nowhere. Computer guided explosives are on your trail, destroy them.... or you're history.'

Port from the Arcades. Looks good.
