Weapon Modification (Scope)

Weapon Modification (Scope) is a weapon modification in Deus Ex that adds a scope to a compatible weapon.

Gameplay
Attaching a scope modification to a compatible weapon enables scope mode for the weapon, allowing for greater ease of use against distant targets. Weapons have perfect accuracy when fired in scope mode. However, there will be some amount of scope sway, depending on the accuracy rating of the weapon. An accuracy rating of 100% will eliminate all scope sway.

Attaching a scope to a weapon decreases the weapon's accuracy by 10% when the weapon is used outside of scope mode. This penalty is not displayed in the inventory interface, and cannot be overridden by additional accuracy bonuses. Therefore, if a scope has been installed, the maximum accuracy that a weapon can have when the scope is not activated is 90%, even if the weapon has attained a nominal accuracy rating of 100%, and even if additional accuracy bonuses (such as the bonus from Targeting) are applied on top of the 100% accuracy rating. Furthermore, the perfect accuracy bonus granted by the laser modification does not apply if a scope has been installed and the weapon is used outside of scope mode.

Due to the accuracy penalty outside of scope mode, attaching a scope reduces the effectiveness of the weapon in close range combat to some extent.

The sniper rifle comes with a scope already installed. Unlike weapons modified with a scope modification, the sniper rifle will have perfect accuracy outside of scope mode when a 100% accuracy rating has been attained.
