Commonly regarded as the ultimate energy weapon, the L30 saw use (post-War) by Brotherhood of Steel Paladins, Unity Nightkin and even Enclave soldiers. (On that note, Advanced Power Armors have a 90% resistance against laser damage, which means the user has to rely on critical hits to deal significant damage against Enclave soldiers).
- Carried by the Lieutenant.
- Two in the Cathedral; one is carried by the Nightkin just after the door requiring the black CoC badge, the other is in a locker on the third basement floor of the Vault in the mutant bunk room.
