I found out about this game way back in the early 2000s, I'm not sure when. It was a two-stage demo that my pc at the time could barely run, and it looked like the 32-bit arcade games at the time. It was unique for having only two weapons and a mix of both for a special, and it stuck with me to the point that I was hoping I'd be able to see it again somewhere.
And it's on steam now, but I'd rather get a drm-free version that will last forever.
