To get the Q-Beam Laser weapon, go to the Hardware Labs and enter the machine shop. Go outside the ship and find the breached section to the right. Locate the Breach Failsafe and fix it (Repair Level 2 required). After the breach is fixed, go back inside and enter the breached section through the Atrium second floor. Use the computer to open the door to the testing range, and grab the Q-Beam Laser weapon. It shoots a concentrated beam of particles and lets the target explode. To get the fabrication plan for the Q-Beam ammo, halfway through the story you will automatically reach the Deep Storage. Once you are inside, use the note on the computer on the right to get up the stairway in the next room and up to the data vaults. Turn right and enter the command center. In the top right corner is a safe with the Q-Beam Cells fabrication plan. The code can be found on a note pinned behind Danielle Sho's computer screen.
