M-22 Eviscerator Shotgun: Before reaching Orion Hall, you’ll find yourself in a large classroom with a shield generator inside. Fight the enemies that show up, then go through the door next to the shield generator. Turn left to find the M-22 Eviscerator on the bench.
M-96 Mattock Assault Rifle: From the Eviscerator, go back into the classroom and take the door directly across from the one you just used (this is the path to your objective anyway). On the other side of that door you’ll see two orange benches back to back. The Mattock is on the right bench.
Mnemonic Visor: Continue past where you found the Mattock and turn left. On a bench, near a kneeling student, you’ll find this visor.
Serrice Council Chestplate: In the room after the one in which you found the amp schematics, hop over the flaming bench section and look to your left. This chestplate is on a bench against the wall.
Armax Arsenal Greaves: You’ll enter a room with multiple levels where a varren attacks one of your enemies. Stay on the lower level and walk forward to the desk to find these greaves.
Sentry Interface: Walk past where you found the greaves, and beyond the ladder leading to the upper level. Eventually you’ll see this on a bench.
M-13 Raptor Sniper Rifle: Get up to the second level and bypass the locked door. Go through, but instead of turning left to fight the enemies, continue forward and around the corner to your right to find this weapon on a bench.
Scorpion Heavy Pistol: When you reach the power terminal, look on the ground nearby for this weapon.
