Q-35 Matter Modulator

The  is an upgraded and unique version of the plasma rifle in Fallout: New Vegas.

Characteristics
It can be repaired using plasma rifles. Instead of using 2 microfusion cells like the standard model, the Q-35 Matter Modulator only uses 1. Its rate of fire is about 2x faster than plasma rifles, and it degrades slower than a regular plasma rifle. It also has about 50% extra DPS. It cannot be modded since its plasma bolts already have similar velocity to that of a regular plasma rifle upgraded with a magnetic accelerator. It also has a dark red and black color scheme as opposed to the normal grey; interestingly enough, the micro-fusion cells used as ammo also follow the color scheme and appear red and black. This causes the cells to appear similar to electron charge packs.

Variants

 * Plasma rifle
 * Van Graff plasma rifle

Location
REPCONN Headquarters, behind the very hard locked door at first floor. The very hard terminal next to the door can also be used. Note: Not always a very hard locked door. Also, in lieu of finding keycards or terminals to upload your facial profile to, it is possible to covertly kill all Mr. Handy "Mobile Facial Scanners" without setting off the alarms--however, you must kill them before they talk to you! The other Mr. Handy models can be avoided or destroyed without alerting security provided you are not witnessed or told to vacate the premises in 30 seconds.

Accessing the weapon without 100 in Science or 100 Lockpick:.
 * Floor 1
 * Take the tour. The tour guide will open the room to the planetarium (average locked door if you do not like the Long tour or the robot is dead) and go to the room back in the left. Walk upstairs and there is a key card for the main floor.
 * Go back to the entrance and enter the room at the right (4 dead fiends in front of it) and walk up the stairs. Go to Floor 2.
 * Floor 2
 * In the room on the left is an easy terminal to add facial data recognition (optional if you have the key card). At the southwest corner of the second floor is a staircase which will guide you to Floor 3.
 * Floor 3
 * There is a Mr. Handy who asks for the password, with a Luck of 7 and higher or Intelligence of 2 or lower, you can say Ice Cream. Otherwise you have 30 seconds to find the next key card (see below) before an alarm sounds, all the Mr. Handy robots turn hostile, and hostile heavy combat bots appear from hidden compartments in the walls. Where the roof collapsed there are lying 2 Brotherhood Paladins (holotape for accessing Hidden Valley) and next to the collapsed roof at the other side (go all the way around) is a skeleton with a briefcase with 200 pre-War money and key card for Floor 3.
 * Back to Floor 2
 * Get to floor 2 again and find the door for floor 1 access (not the main door. Lockpick 75).
 * Back to Floor 1
 * Use the keycard on the door and in the next room (where the floor has collapsed) walk in to it and in the right corner you see the Q-35 matter modulator!

If you can't find the correct door on the 2nd floor, you can also unlock the very hard door on the main floor now with the key card to enter the same room.

If you do not meet some of the stat/skill requirements mentioned above, you can simply kill all the hostile robots.

If the gun is not there make sure to check your companions inventory as they may have taken it before you get to it.

Behind the Scenes

 * The name is a reference to Marvin The Martian's "Illudium Q-36 Explosive Space Modulator" that he requires to complete his planet destroying weapon, in the 1948 Looney Tunes episode, "Haredevil Hare."

Bugs

 * If picked up, the gun could cause problems with loading game, when loading a game, console reads "cannot open file because there are some mods that cannot be held", loosing the entire accounts playing ability.
 * The gun may be wedged in the wall making it difficult to retrieve but if you just go up against the wall in third person you can aim at the ground and grab the gun. Another option is to use C-4 to move the gun until grab it.
 * When dropped, it may become invisible.
 * Sometimes, the gun will not be found floating in the middle of the capsule as shown in the images below. It will be on the floor.
