ADS is an abbreviation used in gaming that stands for "aim down sights" or "aiming down sights". It is most commonly used in first-person shooter games like Call of Duty and refers to the act of aiming with a weapon in first-person view to get a better look at distant enemies. Aiming down sights can also slow down players in some games like VALORANT, and understanding each games mechanics is important to use the ability effectively.

It is important to note that ADS can also have other meanings in different contexts. For example, in MMO games, some players use ADS to refer to additional enemies that are typically easy to kill. Some players will call out these new enemies to their team or group to let them know new enemies have appeared in the area.

In addition, ADS can also stand for "in-game advertising" in mobile gaming. In-game advertising is a revenue strategy game developers employ in which they earn money by selling ad space in their games. These ads can be directly integrated into the game or be viewed as traditional banner ads. Thanks to the revenue generated from ads in their gaming apps, app developers can offer a free user experience while producing the content they love. Moreover, advertisers have a highly effective way to engage users in their ads to acquire new customers for products, services, or other apps.
