Aside from the fact the game (following an extensive teaser) actually has a Bond-style opening credits sequence, the credits include one that reads "Introducing Terrence Sloggins." Sloggins is one of the fat HARM guards who has some (intentionally) badly-acted scenes.
The end credits start over the sound of Cate and Magnus arguing. Later Mr. Jones returns to UNITY to a worn out Bruno. The credits end with the Director hanging up on his mother one last time and then talking to Volkov.
The background of the end credits contain concept art of the game. For instance general Hawkins with a pipe instead of a cigar.
