This game is made by Sega in the year 1988. This is one of the best Sci-Fi-Shooter. You control a spaceship and must shoot all aliens. With the stick you move your ship, with the B-Button you release your satellite and with A you shoot. When you pressing longer the A-Button your shot is bigger. The extra gives you the satellite, which can free flight besides you or docking in front of your ship. When you have the satellite and you catch another extra your weapon will be better. At the end of each level awaits you a big monster.
I know this game from C64, but this version is maybe better. The scrolling and the controls are very good. First this game was a coin-op. The music is very good. But the bosses are hard to destroy. To gear up your extra-weapon makes much fun. Some Enemy-Sprites looks like Alien from the movie. There is also an extra which gives you missiles to shoot.
The controls are good, it is good to play. There is good music in the game.
I played it the first half of February 2020
