an underrated game to be honest! I played through it a bunch of times as a kid, and while it's not going to win any prizes for originality (it was very much a homage to the mindless action-filled FPS games of the 90s during a time when most games were trying to move on from that), it played well and featured some great art design choices!
It's definitely not perfect; like many of the 90s FPS games it's paying homage to, some of its level designs can be rather confusing and unnecessarily maze-like and repetitive. It also has literally nothing to do with KISS besides the player characters gaining powerups that made them resemble the members of the band as they progressed (that, and the title of course, lol).
That being said; I'd love to see it get a second chance. I think people who are really into the whole boomer shooter subgenre are definitely gonna enjoy this one regardless of its flaws.
