Mass Effect Legendary Edition

Im providing a link to the Mass Effect wiki page that lists all of the possible upgrade locations you can find.

Honestly i just picked up all possible finds as i played through each of the missions and got this pretty easily. Theres an in game tracker you can check in Shepards private terminal in the Captains Quarters on the Normandy to see how many you have. Basically, just keep upgrading everything you can as you play the game and you should be fine.

You need to fully upgrade one of your weapons. This can end up being a pain if you were not searching as you play. So keep an eye out for the upgrades. For example if you wanted to upgrade the smg. One upgrade can be found during thane's recruitment mission, another in garrus recruitment mission. One more can be found in Miranda loyalty mission. The others can be bought in the stores or upgraded with minerals. So keep and eye out as you play so you don't miss them. If you do miss one like i did you can go to the shadow broker base after the dlc and get it with the daily delivery. Good luck
