LESUSS: INVESTIGATE ASARI COLONY
Disciple Shotgun: You’ll eventually meet one of the Ardat-Yakshi and have a short conversation. In the next room, take out the cannibals, then look for a smaller office to the right. Check the ground inside for this weapon.
Serrice Council Shoulder Guards: To the right of the Disciple, on a desk.
PRIORITY: GETH DREADNOUGHT
Arc Pistol: When Tali joins you aboard the dreadnought, she’ll essentially give this weapon to you during the cutscene. Just make sure to grab it from the console. Don’t miss out on this one!
Archon Visor: As you make your way through the dreadnought, you’ll find yourself in this corridor. Check the right-hand side to find this visor near one of the consoles.
Geth Pulse Rifle: In the room after the one in which you found the Archon Visor. Again, look to your right to find this weapon on a crate.
N7: FUEL REACTORS
Rosenkov Materials Chestplate: As soon as you have control of your character, turn left. Several meters in front of you, on a crate, lies this chestplate.
RANNOCH: ADMIRAL KORIS
Javelin Sniper Rifle: This weapon lies on the ground just beyond where you found the first dead quarian. Be careful: there is a mine right next to it.
Armax Arsenal Chestplate: If, when you have the choice between two different AA control panels to go after, you choose the right panel, this upgrade is only a few feet from it. Don’t worry if you choose the left panel first; you will have to deactivate both.
Kassa Fabrications Gauntlets: On your way to the upper entrance, you’ll see this on the ground near one of the ladders. It’s hard to miss.
Geth Plasma Shotgun: You can find this weapon on your way to the shield override, just before going back inside the structure.
