Vs. Game

IN THE YEAR 2091, ROBOT CONTESTS HAVE GAINED POPULARITY. ONLY THE STRONGEST ROBOT CAN SURVIVE.

This game is completely lacking a staff roll - after the ending, you're kicked to the high score board, and then to the title screen. However, a number of Irem games do credit the staff members in their high score boards, albeit in an abstract and hard-as-hell-to-identify-these-people manner (as documented here!).
There's little to no chance of actually identifying these people, thanks to the cryptic nature of video game credits... but for now, it's better than nothing.
