Aim down sights

Aiming down sights, abbreviated ADS, is a gameplay mechanic featured in Destiny and many other First-person shooters.

Overview
When aimed down sights, the camera angle shifts to behind the weapons sights. This generally makes the weapon more accurate, and may provide some zoom. ADS is usually used at longer ranges. Unlike most other instances of aiming down sights, weapons in in the game are sufficiently accurate when ADS are not in use, and movement does not appear to be impeded when they are in use either. As of yet, it is unknown if the aim snaps onto enemies when entering ADS.
