Now you might say this is just a coincidence, but let's be clear about what we're looking at here. This, my friends, is the first level boss of both Mercs AND Shock Troopers. Oh sure, airplanes are common place ever since Ikari Warriors, but you can't understate how similar these two pictures are. Even the locale is fairly similar. Thankfully THIS is where the similarities end between the games, but it's a bit odd, don't you think?
