- TRIVIA -

This bootleg of Operation Wolf proved popular as a game in its own right and even outscored the original in location tests. The reason? The lightgun on Operation Bear was a free roaming replica machine gun on a chain, which could be carried more realistically than the mounted joystick of Operation Wolf.
