Microfusion Cell (Fallout: New Vegas)

The microfusion cell is a type of ammunition in Fallout: New Vegas.

Characteristics
It is described as a medium sized energy production unit, a self-contained fusion plant used as ammunition for energy weapons.

Recycling
After firing, there is a chance that spent microfusion cells will turn into drained microfusion cells. These are automatically placed in the player characters inventory. Drained microfusion cells can then be recycled at a workbench back into usable microfusion cells.
 * See: comparison table for chances of drained microfusion cells being produced for each variant of microfusion cell.

Conversion
Microfusion cells can be converted into, and from, other energy weapon ammunition types (i.e. electron charge packs and energy cells) at a workbench, with the appropriate Science skill.
 * Conversion (type)

The player can also pool charges from good cells together to make more powerful variants, which improve damage and bypass more enemy DT but burn out weapon components faster.

Weapons using this ammunition

 * Plasma caster (1 microfusion cell per shot).
 * Plasma rifle (2 microfusion cells per shot).
 * Q-35 matter modulator (Unique plasma rifle, only uses 1 cell per shot).
 * Multiplas rifle (3 microfusion cells per shot).
 * Laser rifle (1 microfusion cell per shot).
 * Gauss rifle (5 microfusion cells per shot).
 * YCS/186 (Unique Gauss rifle, uses 4 microfusion cells per shot).
 * AER14 prototype (Unique laser rifle with a green laser, uses 2 microfusion cells per shot).
 * Tri-beam laser rifle (3 microfusion cells per shot).
 * Holorifle (1 microfusion cell per shot).
 * LAER (1 microfusion cell per shot).
 * Elijah's advanced LAER (1 microfusion cell per shot).

Microfusion cell, bulk
Bulk microfusion cells carry less charge than standard microfusion cells, but are substantially cheaper to compensate. The reduced charge results in 85% damage, but also reduces the strain on the weapon to 85% as well.

Microfusion cell, max charge
The max charge version of the microfusion cell deals the highest possible damage (x 1.5) at the expense of highly increased weapon degradation (x 2.50). Using this ammunition type also negates 10 points of an opponent's damage threshold.

Microfusion cell, over charge
Over charge microfusion cells gives a damage multiplier (x1.25) and negates 5 points of an opponent's Damage Threshold. This comes at the cost of having your weapon deteriorate at a faster rate (x1.50).

Notable locations

 * A large stockpile of microfusion cells can be found at REPCONN Headquarters, behind a locked door (Lockpick 50) on the first floor. Over 700 microfusion cells can be found throughout the building.
 * Cliff Briscoe at the Dino Bite Gift Shop.
 * Knight Torres at the Hidden Valley Bunker.
 * Mick at Mick & Ralph's near Freeside's East Gate.
 * Gloria Van Graff at the Silver Rush.
 * Lacey at the Mojave Outpost barracks.
 * Quartermaster Bardon in the Hoover Dam Offices.
 * Blake at the Crimson Caravan Company.
 * The Great Khan Armorer, southeast of Red Rock Canyon.
 * If you achieve Accepted status with the Brotherhood of Steel, you will be approached by a BoS initiate telling you they placed some recycled ammunition in the box to the left where you enter the Hidden Valley bunker. The box will be replenished with microfusion cells, electron charge packs or small energy cells in various quantities and combinations whenever the player fast-travels, granting a continuous supply of energy weapons ammunition.
 * Having an NCR Emergency Radio, and an Energy Weapons skill higher than your Guns skill, will allow you to call for a supply crate which usually contains an amount of microfusion cells.
 * Fiends armed with energy weapons that use microfusion cells usually carry a large number of them (20-50) when killed.
 * In Vault 22, over 100 Microfusion Cells can be found in the reactor room, in the Common Areas, inside two lockers.
