Audio problem: In the last part of the game, if you play as Fong, Fong's voice will be the one guiding you, not Bruce's.
Bug: In multiplayer Battle mode, you can keep shooting Green Shells over and over again which will forever bounce around the track if they don't hit a player, another shell or item, or environmental hazard. If you have enough Green Shells bouncing around, the game begins to not be able to handle all the activity and the smoke behind the shells will disappear.
Bug: Use Kirby and eat Yoshi so you copy his eating ability. Then eat Yoshi to turn him into an egg. The person playing as Yoshi must quickly mash buttons and the control stick to break out. When Yoshi is free, he will be smaller. This can be done over and over again, making Yoshi smaller and smaller. He can even get as small as a single pixel.
Bug: Zombies-Buried: In the Haunted Mansion, there is part where a book shelf slides back and forth by the wall where you find a hallway you must pass through. The Ghosts are usually waiting on the other side and rush at you the moment the book shelf slides to the side. But sometimes, the Ghosts will be partly stuck to the wall in the hall way and can't move, easily killed with a few shots before unhindered ghosts begin to take their place.
Continuity mistake: In the game's opening scene, MegaMan has blue hair. In the end scene, his hair is shown as black.
Character mistake: After the Duo stage, ProtoMan says "What happend?" Happend should be happened.
Other mistake: If you change your class of character after you die and go back to look at your body, it will have changed to the class you are now. For example if you are playing as a Spy and get killed, then change to a Pyro and go back to where you were killed, your previous body will still be there, it will now be a Pyro.
Bug: If your computer or connection lags too much on co-op mode, sometimes you will lose connection and be removed from the game back to the menu. Sometimes though, when the connection is lost, the screen just turns black with the spinning Pentagram at the bottom as a loading screen, but it just stays there. You are stuck. You have to close the game down and restart it.
Bug: Suburbia: In the last wave, the Patriach will often get stuck against cars and just jump in place, unable to move.
Factual error: When scanned, some women say "I'm afraid of Virginia Wolf", as a homage to the play "Who's Afraid of Virginia Woolf?" The play was first performed in 1962 and the film was released in 1966. The game is set in 1957.
Suggested correction: Virginia Woolf was a well-known author years before the game takes place; although the title is referenced, it was meant as a joke and thus cannot be considered an anachronism.
It is not a joke as the entry pertains to the play itself. The phrase "Who's afraid of Virginia Woolf" was never spoken until after the play came out.
Other mistake: In Goro's bio, the term "ancestor" was used to describe the relationship between Liu Kang and the Great Kung Lao, who was born centuries before Liu Kang, despite the term that should have been used being "descendant." That was probably a translation/spelling mistake.
Bug: During the mission "Davis Unit" after I made the airborne fortress retreat, I was using a Fregeta and I managed to destroy a bridge with two tanks nearby it. The rear tank stopped as it should have, but the second tank actually drove across thin air and managed to reach the center of the gap where the bridge was. After that, it promptly fell to its death.
Factual error: Civ IV includes the famous quote from Henry T. Ford about the Model T being only available in black, this is false on two accounts; First Henry T Ford never said it or anything like it and Second the first Model T was actually green, followed by blue and orange, in fact black wasn't introduced until some years later.
Continuity mistake: At the end of the second level (Scotland The Brave) Cortez picks up a photograph of Crow and Khallos. In the next level (The Russian Connection) you see the picture being taken, and Crow and Khallos have switched places.
Factual error: Dead Kennedys don't use the article "The" in their name.
Other mistake: When talking to Admiral Onasi about Revan in the endgame, the subtitles spell the Admiral's last name 'Onassi'.
Bug: In the beginning training missions (the white rooms). In the mission where you are trying to find a door and guards are walking around underneath you take out the guard in one of the buildings and stick him in the left hand corner (facing away from the door) then throw 1 or 2 grenades at him (this is the only time in the game this will happen). When they land on him and explode all the walls will be covered in red paint (presumably blood) even on the ceiling - this should not be happening.
