In the context of video games, particularly first-person and third-person shooter titles, ADS stands for "Aim Down Sights." This foundational gameplay mechanic allows a player to raise their weapon and look directly through its iron sights, optical scope, or reflex optic rather than firing from an unadjusted hip-fire stance. Utilizing ADS mode typically narrows the weapon's bullet spread, increases shooting accuracy at long distances, and subtly magnifies the player's field of view, though it frequently incurs a minor penalty to movement speed and peripheral vision awareness during active combat engagements.
