For an overview of plasma rifle models in various games, see Plasma rifle.

Semele was an unfinished (though reportedly failed) plasma rifle project, developed by Poseidon Energy.


The technology used in Semele, specifically the Heisenberg compensation field when dealing with matter conversion, was later used to develop RobCo Industries' own model of the plasma rifle, which proved to be successful enough for deployment in the Enclave Armed Forces.


Semele is only mentioned in Fallout: New Vegas.

Behind the scenesEdit

In Greek mythology, Semele (Σεμέλη) was the mortal mother of Dionysus, according to one story of the latter's origin. In most versions of the myth, she asked her lover, the god Zeus, to reveal his true form to her, the sight of which resulted in her immediate incineration.
