Free look

Free look (also known as mouselook) describes the ability to move a mouse, joystick, analogue stick, or D-pad to rotate the player character's view in video games. It is almost always used for 3D game engines, and has been included on role-playing video games, real-time strategy games, third-person shooters, first-person shooters, racing games, and flight simulators. Free look is nearly universal in modern games, but it was one of the significant technical breakthroughs of mid-1990s first-person perspective games. Many modern console games dedicate one of the several analogue sticks on the gamepad entirely to rotating the view, where as some older console games, when gamepads usually had fewer or only a single D-pad or analogue stick, had a feature where the single D-pad or analogue stick would move the view instead of the character whilst the player held down another button at the same time, often labelled in game as the "look button".
