In a 3D video console game, whether third person or first person, the camera is of course a common problem, even without Camera Screw. In combat oriented games, keeping the camera on a target is perhaps the most important thing, hence this trope, which is when the camera locks itself itself onto a target location, moving and adjusting itself to keep the target onscreen while the player moves about. This is usually combined with directing the player's actions relative to the target, allowing them to circle-strafe around the enemy's attacks and quickly return fire.
