Character mistake: In the Sega CD version, during the opening scene, a guard is grabbed and says, "I'm a Kleindast's guard." Using the name of a character Kleindast possessive but in a bad grammatical way. It should either read, "I'm just one of Kleindast's guards!" or "I'm a Kleindast guard!" without the possessive status.
Character mistake: On the German level, it says Kleindast commands a Nazi regiment which uses modern "weaponly" instead of weaponry, with it spelled wrong.
Character mistake: Level 4 is listed as "German" instead of "Germany" like it's supposed to be. Just German.
Other mistake: In the opening text under Dr. Kleindast, it quotes him as saying "Let the duel begins" rather than "begin" as it should be, making it grammatically incorrect.
