Continuity mistake: In the ending cutscene of the G5-Building level, you will see you have come out of a plain wall, which you blew down before completing this level.
Continuity mistake: In the 2nd DataDyne level when Joanna punches the guard in the elevator, the guard is facing away from the elevator door and has his head below the wall. But in the next level, when the guard wakes up, he has his head down below the door, even though he was supposed to be unconscious.
Continuity mistake: In the first DataDyne level, when the player punches Cassandra in her office, the necklace isn't on Cassandra's collar because the player has it. But then in the G5 Building level when the player sees Cassandra in the meeting room via Camspy, the necklace is back on her collar.
Other mistake: In the final level, Mr. Blonde's Revenge, Mr. Blonde is the player, but several guards say "get her" before shooting the player. This mistake also happens when you play any level with Velvet as your buddy, because she says the same thing before shooting the guards.
