Weapon Modification (Scope)

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

Description

A telescopic scope attachment provides zoom capability and increases accuracy against distant targets.

IN-GAME DESCRIPTION

Effects

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, the player's view in scope mode is affected by scope sway (also known as scope shake), the amount of which depends on the accuracy of the weapon. An accuracy of 100% will eliminate all scope sway.

Accuracy penalty outside of scope mode

Attaching a scope to a pistol or stealth pistol will decrease 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, the maximum accuracy that a scoped pistol or stealth pistol 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 is fully negated when a scoped pistol or stealth pistol is used outside of scope mode.

This penalty only applies to the pistol and stealth pistol, which are hitscan (instant-hit) weapons. This penalty does not apply to the mini-crossbow, plasma rifle, and GEP gun, which are projectile weapons. The sniper rifle, which comes with a pre-installed scope, does not suffer from this penalty.

Magnification amount

The amount of magnification given by the scope varies depending on the weapon, and is governed by the weapon's ScopeFOV property. A lower value of ScopeFOV corresponds to a higher amount of magnification.

Compatible Weapon	ScopeFOV
GEP Gun	10
Mini-Crossbow	15
Plasma Rifle	20
Pistol / Stealth Pistol	25

The sniper rifle and binoculars have ScopeFOV values of 10 and 20, respectively.
