Metal Slug?
Looks more like an ork fightabomba to me...
Reviews for "Slug Plane"
Nice...
Good spray silver effect and cool random desine.
Yet again, I'm fairly certain this was an older drawing. It's still a nice drawing. It just pales in comparison to your modern stuff. It really does seem to be from a different artist. I guess you were just experimenting back then. It looks kind of silvery.
It's probably just a shiny metal. I like the little guns sticking out. I just now notice the screws. Even your early stuff is above average. Then again, most of the stuff I review is just plain good.
