MPLX Novasurge

The MPLX Novasurge is a weapon which is added to Fallout 3 in the Mothership Zeta add-on. It is a unique version of the plasma pistol.

Characteristics
The weapon acts very similarly to the plasma pistol it formed the basis for, barring several prototype features. First and foremost, this weapon does more than three times as much damage as the regular plasma pistol and has a higher critical multiplier (3x as opposed to 2x). However, it uses two energy cells to power each shot and weighs twice as much as the normal plasma pistol.

Durability
The MPLX Novasurge can fire a total of about 188 times, the equivalent of 24 reloads, from full condition before breaking. That's 212 times fewer than the common plasma pistol.

Variants
Plasma pistol - The common variant in Fallout 3.

Location
The weapon is found in the cargo hold area of Mothership Zeta. In one area is Reid Underwood's terminal (a Hard lock), which can be hacked to unlock a safe. To get to the terminal, go to the research lab door, go north then a bit east, and one should see a group of terminals. It will be the only one that isn't broken. The safe itself is found in another area among several piles of rubble, next to a machine that is dropping items into a pit. Inside the safe is the weapon, a note detailing the weapon and energy cells (amount may vary due to the Scrounger perk).

The cargo hold becomes inaccessible after teleporting to the bridge, making it impossible to obtain the weapon afterward.

Bugs

 * While using V.A.T.S., selecting a target causes the ammunition counter to drop by one, not two. The bolt will still use two energy cells, but this may force an unexpected reload sequence.
 * Sometimes Paladin Hoss will unexpectedly show up (even though he's not supposed to) and take the pistol after one has unlocked the safe.
