In the "Die Hard 1" part of the game, in Level 7 Executive 1, there is one hostage who is killed within seconds after the start of the level; the only way to save him is to immediately proceed to the meeting room and kill the terrorists without hitting the hostage. Based on the look of this level (a floor filled with models) and the location of the hostage (meeting room), he is presumably meant to represent Mr Takagi from Die Hard (1988), who was executed by Hans Gruber early in the movie.
The gaming disc also doubled as a soundtrack CD.
