Ahh Apogee games, some of the best games I never owned. Specifically when it comes to this shooter gem.
I played the hell out of Raptor's Shareware version back in the day and it always filled me with a sense of excitement and reward. Everything about the game from graphics to gameplay was superb and most importantly for me I didn't have to have hardcore reflexes to play it(something that for other Japanese shooters was required).
If you've ever been curious about this type of game, Raptor is surely the most comfortable way to break into the genre.
Cheers to GOG for getting this and more raised glasses if you can manage to get Terminal Velocity and Wacky Wheels.
