I remember the shape of an enemy in a shmup, but I just don't can't remember from what game.
I'm not even sure if it was an enemy or just a background ship you flew over.
So here comes my description:
It is big ship and you see it from above but at the back you can see the engine? (I mean the part where the boost comes out). It has a slightly isometric feel.
I have made a sketch to show you what I mean:

I know this is really a bad explanation, but that is really all I can remember.
I'd like to rip the graphic to use it for my own shmup project, but I can't find this ship.
