Armor Upgrades in Mass Effect 1 are special tools that are slotted to the equipped Armor of the player and his Squad. Slotting an Armor Upgrade provides both offensive and defensive enhancements, making the equipped Armor even more effective. High Tier Armor may have two slots available for further customization. Armor Upgrades can be purchased from Merchants or looted from containers.
As all Equipment in Mass Effect 1, Armor Upgrades come in a variety of sophistication levels. Notice that not all Armor Upgrades come in all the 10 levels.
Armor Upgrades can be equipped from the Equipment Menu. While viewing currently installed item, press X to enter the upgrade screen.
