The Compliance Regulator is an electroshock weapon and a unique version of the standard laser pistol, in that not only does it fire a blue beam instead of the normal red, but dealing a Critical Hit upon an enemy will paralyze them for 10 seconds. It also does not have a handguard like other laser pistols.
The Compliance Regulator can fire a total of about 995 times using standard cells, the equivalent of 34 reloads, from full condition before breaking.
With the perk Laser Commander, the critical chance is raised by 10%, which gives a higher probability of paralysis.
It is considered an improved holdout weapon and, with a Sneak skill of 50, can be brought into weapon-free areas such as casinos.
Despite dealing only a small amount of damage, the stun effect enables players with a decent critical rate to kill enemies vastly more powerful than themselves, since the fire rate is high and most enemies are not immune to the stun effect.
Scoring a second critical hit on an already paralyzed enemy can extend the duration of paralysis.
As the main draw of this weapon is the Crit effect, not the damage, use it with Bulk Ammo, as this will cause less durability loss. This can also generate Drained small energy cells for recycling; more with Vigilant Recycler.
It's possible to freeze yourself with the gun if you have the Meltdown perk. If the killing shot is a critical hit, and you're in the radius of the Meltdown explosion, you will paralyze yourself.[verified]
Strangely, it always cripples the limbs of spore carriers in one hit, allowing you to cripple all of their limbs without doing a great amount of damage.[verified]
