Carrier: After Bond plants his mobile phone on the EMP-hardened helicopter, the player still has access to it for the remainder of the level.
In Archives, Ourumov fires two rounds from Bond's P99, flicks two more out of the magazine, and then throws the gun to him. When the player is given control this has emptied the 16-round magazine.
In both Memorial and Cradle, Bond gives his P99 to Natalya and still has it when gameplay resumes.
Archives: Ourumov can be heard giving an announcement over the PA system when he has already left with Natalya.
At the start of Bunker, Bond calls Tanner, who replies normally. The game then zooms in to show Bond's phone has no signal due to the EMP, and is full of static.
The name "Janus" is mispronounced throughout the game. Every character says it like "janice", but the proper pronunciation is like "yanus." Strangely, Judi Dench mispronounces the name in this game despite having pronounced it correctly in the 1995 Goldeneye feature film.
Due to copy-pasting of geometry, one of the debris fields surrounding the crashed MiGs in Outpost contains at least three wings.
Soviet-era posters are seen throughout both versions of the game, despite it being set long after the fall of communism. Busts of Lenin and Stalin can be found in Archives, which would never be in a government building in modern Russia.
A large statue, "The Motherland Calls," can be seen in the Wii version's Memorial Park, set in St. Petersburg. This statue is actually in Volgograd, a thousand miles away.
