The 1980s were a pioneering time for video games. Game designers had a wide open field, lacking the constraints of "established" parameters. The possibilities were seemingly endless, and, with a little brainstorming, could form a nexus of boundless creativity. Instead, game designers said, "what if we just took the Bionic Man and smashed it together with the plot of Commando," then took a long lunch.
In Japan, where they are a little more creative, they said, "hey let's make zombie Hitler."
Thus was born Bionic Commando. According to the instruction manual, the 1987 game is set in the year 198X:
Which means it's set in the near future, as long as X equals 8 or 9.
You would think this premise would be enough for an entertaining game. This was, after all, 1987...the best-selling toy was a baby crossed with a vegetable that gives you severe gas. But no, the killing of man was apparently no longer a thrill to hip 1980s kids, and so they had to make everything Nazis.
At least, that's how it was in the Japanese version. Meanwhile, Nintendo of America was establishing its reputation of being totally against everything National Socialist, as long as it didn't mean spending any more money. So, a series of lazy changes were made: Hitler was changed to "Master-D," and the Nazis were changed to "Nazz," as seen in the above instruction manual. Still, the art assets remained pretty much the same, so you still beat the game by making Hitler's head explode.
