Ammunition Upgrades in Mass Effect 1 are one of the upgrade categories of the game and are specifically designed to enhance the effectiveness of your weapon's ammunition granting different effects like poison, cold, and burn. Ammunition Upgrades may also generate negative effects on your Weapon such as a slow rate of fire or increased heat generation. All Weapons have one or two open slots for Weapon Upgrades and always one for ammo except Weapons from Geth Armory that do not accept any kind of upgrades.

A weapon can only have one type of ammo at a time, while several weapon upgrade mods can be installed to dramatically increase its performance above and beyond stock levels. Ammunition Upgrades can be purchased from Merchants, looted from containers, and also can be dropped by killed enemies or bosses.

Sophistication Levels

As with all Equipment in Mass Effect 1, Ammunition Upgrades come in a variety of sophistication levels. Notice that not all Ammunition Upgrades come in all 10 levels.

Installation

Ammunition Upgrades can be equipped from the Equipment Menu. While viewing the currently installed item, press X to enter the upgrade screen. To equip a weapon upgrade on PC, go to Inventory (I) and click on one of the boxes next to the weapon manufacturer and name of the weapon. From there, there will be two boxes, one has gun modifications and the other has ammo upgrades.
