Back in the days when plot was secondary to the fun, a game called Starglider was made. As the title suggests you’re in command of a glider that’s among the stars and you need to blast the living daylights out of everything in site.
You’ve got two types of weapons. There’s the canon and there’s the missile. When you fire a missile you get to guide it to the target, when you fire you simply hit what you aimed at. Just make sure you didn’t fire the missile in vain (and I’m not kidding with this one)!
Some targets require more shots then others, some will even fire back. Some are really though, and trust me, the further you progress the tougher they get.
The controls of the game are simple. You move up, down, left, right and shoot (fire a missile). There's a compas on the top of the screen showing your heading and there's a radar screen at the bottom, showing the bandits you need to shoot.
The sounds are basic but do the job (you get different sounds for hitting into stuff and blowing stuff up). Graphics include only four colors, but you get to select the CGA color palette at the beginning of the game, where you also select your input device. Oh, and before I forget, the first thing you get to select is the language (the game is in German and English), not that there’s much of it.
It’s a nice little shoot-them-all-up game, but I’m not sure how long you’ll be able to stare at the purple dots moving all around, before you’re eyes start to hurt. Still the game gets an average mark of three, because apart from the 3D feel (which wasn’t new anymore at the time) the game doesn’t offer anything some other shoot them up wouldn’t.
