Of course that's a conversion. That's what I hate about KLOV. These idiots submit all sorts of photos that aren't original and it messes up an otherwise useful "documentary" tool.

Midway stopped making cabinets like that around 83. Maybe 84. Dead Angle is made by FABTEK in 88. Completely unrelated, so definitely a conversion.
But hey, thanks for letting me know about this game! I like Empire City and never knew it had a sequel!
