This weapon has a Strength requirement of 8 to use effectively and uses electron charge packs as ammunition. It deals very high damage per second (DPS), particularly when used with a high Energy Weapons skill, focus optics mod and max-charged or over-charged ammunition.
The Gatling laser achieves a high DPS by firing multiple low powered lasers at an incredibly fast rate, about 1800 rpm. It consumes ammunition at an equally incredible rate, depleting a full battery of 240 electron charge packs in just 8 seconds. Like any Energy Weapon, Gatling laser automatically ignores 2 DT while using regular electron charge packs; this value raises to 5 with over charge electron charge pack, over charge and even to 10 with electron charge pack, max charge.
The Gatling laser is incredibly effective against un-armored foes such as Cazadores, night stalkers and feral ghouls. When used with max charge ammunition, even deathclaws can easily be killed with this weapon. Its damage can be raised to 23 with focus optics and the Laser Commander perk while using max charge ammunition. It can be raised further to 28 with ED-Ecated upgrades from the Divide. Considering -10 DT effect from max charge ammunition, the Gatling laser is highly effective against medium armored enemies as well.
Compared to the Gatling laser of Fallout 3, it has significantly higher DPS and ammunition consumption rates. With the carbon fiber frame mod the weapon becomes remarkably light weight at 9 pounds (identical to the tri-beam laser).
The Gatling laser model includes a large metal pack that appears on the back of anyone using it.
The Gatling laser with all mods and max charge ammunition is extremely effective against NCR troopers (excluding veteran rangers) and Caesar's Legion legionaries (excluding centurions) due to the fact that their armor usually has a DT below 10, allowing you to kill them in less than five shots in some cases. This is very useful if you want to kill Caesar or wipe out Camp McCarran or Camp Forlorn Hope, thanks to the lack of rangers and centurions in those areas.
A Gatling laser with the focus optics mod, associated perks, and MC ammunition has an exceedingly high DPS rate.
If you have the Lonesome road add on, the focusing optics mod, rank 4 of the perk Camarader-E, and the laser commander perk, the Gatling laser will exceed the Sprtel-Wood in Damage per second - with optimized ammo, it is over 700 DPS.
pcps3xbox360 Sometimes, the backpack or the weapon won't disappear when changing to a different weapon (this happens when the Gatling laser backpack is on and you switch to a different set of armor). Switching back and forth between the Gatling laser and some other weapons while having them holstered seems to fix this whenever it occurs. [verified]
pcxbox360 When wearing Remnants power armor, or its unique variants, you can see through parts of the battery pack, showing the orange fan through gaps in the warning signs, etc. This is a limitation of the game engine that allows to alpha layers to cancel each other. [verified]
pcxbox360 The high voltage warning sign's edges on the backpack appear to be transparent. This is proven by going into a low light area, then focusing the camera on a bright object in the background. This also applies to the Gatling laser of Fallout 3. [verified]

xbox360 Sometimes, if equipping with both mods and the Laser Commander perk, the weight increases back to 18 lbs. The weapon will show 9 WG, but your carry weight will increase by 9 lbs. Unequipping will again reduce the character WG 9 lbs. [verified]
