Character mistake: In the opening cinematic (before you press start), the group hears a witch crying, and Bill and Zoey go to investigate. Louis and Francis stay outside to keep watch. When, in the dark, Bill and Zoey approach the witch, Zoey puts her flashlight on the witch and Bill immediately says, "lights off!" Now here is the confusion - Bill knows it's a witch, so shouldn't he know what they sound like and not enter the room in the first place?
Continuity mistake: Mob Rules: When Martin runs into the road and tells Ned to stop his car, there are two white lines across the road in front of the car. After Martin drives off, the two white lines across the road have suddenly vanished.
Continuity mistake: In the game's opening scene, MegaMan has blue hair. In the end scene, his hair is shown as black.
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.
Revealing mistake: When fighting Gohma on Dragon Roost Island, when Link uses the grappling hook to grapple Valoo's tail, some of the rope goes through the tail as it wraps around.
Factual error: With the special key, Claire can alter her clothes to a costume that is equipped with a Colt Single Action Army. But still she can fill it with 9mm parabellum which would be impossible.
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.
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.
Other mistake: After the Duo stage, ProtoMan says "What happend?" Happend should be happened.
Other mistake: Some enemies wear cloth hats. If you shoot the hat it will fly off. Look at the hat on the ground. Where you shot it, it shows a metal bullet hole, on a cloth hat.
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.
Factual error: Dead Kennedys don't use the article "The" in their name.
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.
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.
Bug: In level one, after you receive the elevator code and use it to open the elevator, look at the reflection of the elevator doors on the back wall. Even though the elevator doors are open, the reflection shows the elevator doors are still closed.
