There are 40 'crooks' in the game and they are separated by color. Most of the main enemies (all named after terrorists in the movie) wear blue and always carry an MP5 submachine gun, a spare clip and a CB radio. There are also green terrorist that often carry a spare clip or a soda. The only two terrorists that don't fall into these categories are Hans Gruber and Karl. Karl wears white and will hunt down John McClane towards the end of the game to retrieve the detonators. Hans is the last enemy you fight and is found on the 30th floor with Holly hostage. The objective of the game is to kill every terrorist before they break into the Nakatomi vault.
