Shadowhawk is a comic by Image Comics (or rather their sister studio, Shadowline), a studio set up by people who worked for places like Marvel, but wanted to retain copyright of their creations. Jim Valentino was one of those people, and he created Shadowhawk, an anti-hero who went on a vendetta after getting attacked and infected with HIV. This comic came out during the explosion of the medium in the early 90s, and I have to admit that I was not into it at all.
Valentino, seeing the success of the 16-bit era consoles and a crossover with Shadowhawk's main audience, apparently decided to finance the creation of a video game. However, it never saw the light of day, much like other games based on lesser known comics, such as Prime and Firearm.
The game is split into two modes. It featured one or two platforming stages, followed by a Mortal Kombat-style boss fight. After beating each level, you get a cut scene with the story, and usually a hint at who the next boss is.
