I hope somebody know this one.
It was a PC Shooter, horizontal style like gradius, I remember the first stage was very brown, a endless line of brown mountains and a cloudy and also brown sky.
If memory serves well the first boss was a ship who looked a lot like Frieza's ship from DBZ.

Also, my brother says it was called Fulminator but google don't recognize it.
