Continuity mistake: In the game's final cut-scene, even if you had the M4, Niko will be armed with an AK-47.
Continuity mistake: During the Kronos campaign as Chaos, Eliphas the Inheritor can "ascend" to his final Demonic form. However, despite the in-game unit being granted a different, more appropriate voice for his new body, Eliphas still uses his old one for the various bits of communication that go on between him and the other faction Generals.
Continuity mistake: In the scene where Marshall has to jump over multiple small robots, if Marshall misses a jump and is killed by a robot, the robot turns orange, no matter what colour it was before.
Character mistake: During the exchange level (first level) if you jump in the truck and the guards don't notice you, you'll eventually get to the gate. You'll hear the guy driving the truck say that there are 20 cases of wine. But if you count all the cases there are only 19.
Continuity mistake: When Kairi and Sora finally meet again, Kairi hugs Sora. In the first shot, Kairi's arms are over Sora's. However, in the next shot, her arms are under his.
Other mistake: At the end of the game, "proved" is spelled "prooved".
Other mistake: Go to the Day-Care Man. When he asks you if you want him to care a Pokemon for you, answer YES, but in the Pokemon list, press B to cancel. He'll say "All right then, Come again." However, the "Come" shouldn't be capitalized, it should be "come". This happens because this is a shared text, so when you answer NO to his question, he'll say "Come again", and that's why it is capitalized for this text. However, it is still a mistake. This was made due to a similar text error in Red/Blue, but this mistake was created.
Other mistake: On the PSP version of the game, you play as Optimus Prime, and you have to escort Bumblebee down the freeway. This game follows the movie very well. By this part in the game, Bumblebee should have transformed into the newer 2008 or 2009 Camaro. But he is still in his old 1970's Camaro form.
Bug: On the road between Talewok or Gwernia and Erromon, there is an enemy rat that can cause the game to crash. When you come to the area with three signposts near a big lake, you're close to where he is. If you found this area earlier, it's the same spot where that hilarious cinema scene with the guy in the forest who was afraid of monsters occurred. Follow that path around the bend, through some pine trees, and you should come across a Giant Rat at the top of a hill. Try to avoid this enemy! Whenever I engage him, he causes the game to crash. I'm not kidding! The screen goes blank, and some text shows up and it actually says something like, "System Crash", and then some other text that makes no sense to me. My suggestion is to save near the signposts, then try to sneak past that enemy. If you engage him and nothing happens, don't worry about it. But if your system crashes, there IS another way to get to Erromon. You'll have to look for an opening in the wall along the road (you'll pass through some pine trees.) You should pass a treasure chest along the way. You'll emerge out onto a high plateau with another treasure chest. There's like a round, stony area in the middle of the plateau. You'll have to run down off of it and find the road. Continue taking the road West to Erromon.
Factual error: After the last verse of "Smoke on the Water," there is a guitar solo that's not present in the master track.
Bug: When magnetic ceilings are found, and you fly towards the ceiling, while in midair, pause and take off the iron boots. You will be able to walk without iron boots.
Other mistake: After you defeat Jenova-Life, it says "Beacause you are a puppet." "Beacause" should be "Because".
Bug: In Hollow Bastion, right after you defeat the Maleficent Dragon and before you fight Riku/Ansem, during the movie scene where Sora sees Kairi on the ground in front of the keyhole in the hall containing the Princesses of Heart, Sora lifts Kairi and shakes her up and down to wake her up. The pendant on Kairi's necklace stays suspended in the air when he shakes her until the shot changes.
Continuity mistake: On the final mission, once you kill the final boss, the gun you will be holding in the cut scene is a M4, even if you used a different gun.
Other mistake: When you are at the X-games and doing the street contest, at the first spot there is a cameraman that floats about three feet up in the air next to the halfpipe.
Bug: On the second floor of the house in Rangoon in which a man asks you to fetch his three llamas, you can walk through the right wall and walk around in the black border surrounding the room.
Bug: In the few instances where you can hit Marshal Jackson with the lightning cheat, he remains upright even after being depleted of his 2,500 life points. (I've tried that stunt in El Paso).
Other mistake: When using the skeleton rip fatality on Sheeva, the skeleton always has two arms, despite the fact that Sheeva has four.
Bug: After getting all 120 stars and using the cannon to get to the top of the castle, if you walk around enough at the highest point you will fall through the roof and into a hidden dimension of the front wall. Going through the door itself will not let you escape, so you must jump through the wall to reach the outside.
Bug: In the Mars Lighthouse, in the same room you defeat the Flame Dragons in, return after you have defeated the Flame Dragons and fire off the cannon. A crack will appear where the ice was, even though there is no ice.
