Mass Effect 3: Weapons - list of all Mass Effect 3 guide, walkthrough
Last update: 29 October 2022
This page of the guide lists the weapons available in Mass Effect 3. You'll learn where to buy or find new weapons, as well as what categories of items they represent.
Notice! The table seen below is only about the weapons you may find during the singleplayer campaign. In the multiplayer mode (Galaxy at War) the only way to obtain new weapons is to keep purchasing crates with random equipment, hoping for good luck. The last column of the table explains how you can receive/find/buy a certain weapon.
Notice! The prices aren't displayed in all rows of the third column, because only some weapons can be purchased and the rest must be found or received while completing missions. If you don't see the weapon on the store's list make sure that you don't already have it or try visiting the same store later in the campaign (after completing one or more main quests).
