Disambiguous This article is about the locations of mods, weapons and armor in single-player Mass Effect 3. For a similar guide for Mass Effect 2, see Upgrade Guide. For equipment generally, see Equipment. For armor information, see Armor Customization (Mass Effect 3). For information on mods, see Weapon Mods.

This Equipment Guide details how important collectibles such as weapons, weapon mods, armor, intel, and Citadel mission items can be acquired during gameplay throughout Mass Effect 3. Many items can be found during missions while others can be purchased from the various merchants on the Citadel and a few other select locations.

Legendary Edition: All content for the Mass Effect trilogy that was previously available only from Downloadable Content (DLC) is now included by default. Legendary Edition features many differences from the original trilogy games, including multiple changes to how certain equipment that is DLC-exclusive in the original games is obtained, especially in the latter two games. Differences between versions should be marked with orange notation.
