Space Trek (cocktail) - MAME - Shoot 'em Up

Space Trek is a vertical shoot-'em-up similar to many on the market at the time. Players control a space ship and can move anywhere on screen but can only fire upwards at enemies. There is also a button to temporarily give the ship a protective barrier. There are several rounds of gameplay all with slightly different aesthetics. Space Trek is thought to have been a predecessor to SDI: Strategic Defense Initiative.
