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: During the first cutscene of Phoenix Fire you can notice that the gun 007 takes is a Walther P2K, but when you start playing the game it is a different gun.
