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.
This weapon is extremely useful for pacifist players since ammunition is easier to obtain than purchasing "12 gauge bean bag" rounds, and can be found easily early on in the game. Unlike the 12 gauge bean bag round, critical hits are necessary; however, sneak attack criticals will always cause an enemy to be paralyzed. One can also use Bulk cells, which have three advantages for the pacifist: It does less damage without impacting critical strike chance reducing the chance to kill, it causes the weapon condition to deteriorate at a slower rate, and it is cheaper.
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 no enemy is 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.
