Quadnet's graphical gimmick remains impressive, giving an 70s futuristic tech vibe similar to the HUD in the Falcon's turrets in Star Wars. The gameplay is still fun today, the game is freeware, and it can run well on dosbox with a phone, or on retro handhelds. It is one of my favorite score attack games of all time, and the main reason I still use DOS emulation on occassion.
It's a simple, fun, arcade shooter with vector graphics...a good old game that holds up well today.
