The Desert Eagle is seen in the hands of mostly the Lycans. The first one to carry the gun was Trix, and it was his gun that Selene took back to Kahn in order for him to analyse the new UV rounds. Eventually, Lucian is seen taking up the Desert Eagle and loading up on UV Rounds in order to combat Viktor and his Death Dealers. He's then shot by Kraven's Heckler & Koch USP MATCH loaded with Silver Nitrate Ammunition.
Underworld: Evolution[]
Other Desert Eagles are seen in the arsenal of Andreas Tanis at the monastery.
