Weapon Modification (Accuracy)

Weapon Modification (Accuracy) is a weapon modification in Deus Ex. It is used to increase the accuracy of compatible weapons.

Gameplay
As with other attribute-upgrading modifications, up to 5 accuracy modifications can be installed on a particular weapon, each providing an additional increase in accuracy.

The accuracy bonus from accuracy mods will stack with the accuracy bonus from the corresponding weapon skill. A combination of weapon skill and accuracy mods can be used to attain 100% accuracy for a particular weapon, as shown in the table below. For example, the assault rifle attains 100% accuracy with the combination of 3 accuracy mods and a master level rifle skill.

Once a weapon has attained 100% accuracy, additional accuracy mods will provide no further benefit. Note that at master level rifle skill, the sniper rifle will have 100% accuracy without the use of any accuracy mods. The accuracy gain per upgrade is slightly variable due to rounding. Additionally, weapons with a lower base accuracy gain more accuracy per upgrade as compared to weapons with a higher base accuracy. For example, weapons with 60 base accuracy receive an increase of +3 or +4% per upgrade, whereas the sniper rifle with 75 base accuracy receives an increase of +2 or 3% per upgrade.
