L30 Gatling laser

The  is an energy weapon in Fallout, Fallout 2, and Fallout Tactics.

Fallout and Fallout 2
Commonly regarded as the ultimate energy weapon, the L30 saw use (post-War) by Brotherhood of Steel Paladins, Unity Nightkin and even Enclave soldiers (even though Advanced Power Armors have a 90% resistance against laser damage, which means the user has to rely on critical hits to do significant damage).

Fallout Tactics
While not as efficient as the Wattz 2000 or the Winchester P94, the L30 can still chew apart anything in one or two bursts. A great support weapon, especially in CTB mode.

Locations
