The Recurring Types of Auto-Aiming
When the player points the reticule near an enemy, it automatically pulls towards the enemy, closing the aim:fire ratio gap.
When the player fires while aiming near enough to an enemy, the bullets will go straight to the enemy instead of where aimed. The aiming reticule is not moved.
The player uses an input method to trigger a lock-on; the reticule automatically shifts to the nearest enemy and often allows the user to aim at specific parts of the target.
