there is no such level in the original game, however the is a game shark code that unlocks extra levels that were not intended for the final release of the game.
Really it's a matter of what you want out of either game. Goldeneye 007 is almost nothing like the original N64 game. It has been modified to match Daniel Craig's persona of Bond and as a result has altered the entire game. If you are looking for something new out of the 007 video game franchise than you should definitely go for Goldeneye. However, if you were looking for an exact remake of the N64 version, don't waste your money and go for Black Ops. Do not get me wrong, both games are absolutely amazing, but it's all up to what you want out of either game. If my response has failed to effectively answer your question than please do not hesitate to contact me for a more in depth discussion.
A goldeneye n64 speedrunner
Most likely not. the industry has only been making the new ones on the most recent movies. if you want to play it I'm sure there is roms for it and a n64 emulator.
Goldeneye for the Wii has much better graphics, and a developed storyline. But I still prefer the original for the N64 for its simple-ness
