Q-35 Matter Modulator

The quantum plasma modulation matter injection rifle version 35 (or simply Q-35 matter modulator) is a prototype 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 ammunition 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 Mister Handy "Mobile Facial Scanners" without setting off the alarms—however, you must kill them before they talk to you! The other Mister 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:. Go Directly to Floor 2. Look for the Door that says 'Enter Repconn Headquarters Main Office Floor'. There will be a hole in the ground and you can jump down and the Q-35 matter modulator will be levitating in its storage case. To get back out if you do not have the skill levels mentioned above, you can just climb back up the rubble and back into the second floor. Additionally it is possible to obtain the weapon by going to the third floor and searching the brief case found near the Brotherhood of Steel paladin's corpses, it contains a keycard which grants access to the room with the Q-35 matter modulator.

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.

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.
 * Often, 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 beside the container.
 * When placing the weapon on the floor, it will become invisible making it hard to find in open spaces. Text still appears asking whether or not to pick it up.
 * Sometimes the gun will appear stuck in the bottom of the container making it difficult to get. Sometimes leaving the building then reentering will fix this.
 * May crash game when placed in the purchasable weapons trunks in the Lucky 38 Presidential Suite.
