Nearly all versions of this game have cover art and also other artwork showing a very specific unit shoulder patch on the shoulder of each counter-terrorist operative. The specific unit patch is very distinctive -- it corresponds exactly to the French National Police counter-terrorist unit, Group d'Intervention de la Gendarmerie Nationale.
Also, the operatives are shown using ropes to descend walls and smash through windows --- the same approach that was used when the SAS rescued those who were taken captive in the British Embassy near Princess Gate. And the helicopter being used in the game is the type called the "Little Bird," the same type that was used when the American hostage Kurt Muse was rescued from prison during the invasion of Panama.
Alcatraz from Infogrames is the sequel to this game.
The original french release of this game (maybe others) contained a set of three transparent stickers. The stickers were supposed to imitate bullet holes when applied on a window or glass.
