Mass Effect 3: Weapon modifications - Basic information Mass Effect 3 guide, walkthrough

Last update: 29 October 2022

This page of our game guide to Mass Effect 3 contains complete information about upgrading weapons. We explain how to upgrade weapons, how to get new upgrades and how the process of installing upgrades works.

Each weapon you posses has two slots for weapon mods. There are several types of upgrades and naturally you should be using the ones that suit your style of play and allow you to make the weapon even more useful. I recommend that you carefully explore all areas during the course of the game, because only a small number of weapon modifications can be purchased in stores and the rest you must find on your own.

The easiest way to upgrade a weapon is to interact with a special weapon modification station. One of the stations can be found on board the Normandy (screen above), however you may also find stations while completing main missions. Once you've interacted with the station you must choose the weapon you plan on upgrading and then click on the modification button.

The game will always inform you what you can expect by installing a certain upgrade and you'll also see the difference on five bars that are about the weapon's properties. It's worth adding that if you've found a new upgrade of the same kind you won't have to use the modification station again, because it's going to be improved automatically.
