[Flakorama]

Hello everyone, I'm Flakorama,

I'm new to the forum and I've got this vague memory of a coin-op game I've hardly played once or twice but it got stuck in my head during all these years. You are a time traveller sorta guy who guns down bad dudes and wrecks whole buildings in a Wild Guns fashion, you only see your character from behind, like facing the background, and the screen continuously pans to the right. I remember one boss being a breed between an ironclad and a early WWI tank with two turrets. You also can hurl grenades and do a roll maneuvre to avoid fire. Any thoughts?
