It was a shoot em up game where you played as this blimp looking thing. At the top of the screen was a maroon score box that kept your score, life, and stuff like that. The life bar was in the top right corner and it was like rainbow colored. I can't really remember too much about the game except that it was really great but I forgot the name to it. If anyone has any screenshots of what I'm talking about, it'd be greatly appreciated. =)

*Edit*
For the Sega Genesis. Sorry I left that part out

If you could let us know which Sega console it was on, it might narrow the field down a bit.

Maybe Fantasy Zone on the Sega Master System?

I'm so sorry. I did leave that part out. Usually when I say sega I refer to the sega genesis

Steel Empire was the game, thanks to the Nick Arcade show for helping me find it.
