When Uigig lists of victims, Kac alludes to director of the corporation which causes the events of "Cuando nieva sobre el hielo del infierno". Both characters are played by the same actor Aitor Sánchez.
Both short-films were shot in the same location, with similar camera shots; both show throughout the full duration a couple speaking while dining at a table; and both the actress is Ruxandra Oancea, cinematographer is Pedro Jaén R. and assistant is Wilma Menelik.
The logo of the corporation (I.R.I.S. Global) is the same in both films; and the hologram, which Aitor Sánchez looks in "Orpheize", is similar to that he looks in viral video of "C.N.S.H.I."
The beginning with a lone traveler in a snowy wasteland searching for a creature is an homage to the one that appeared in this earlier movie by the same author.
The Cross-Cutting of the opening credits, and some of the shots of dialogues, the approach of the ship and the attack of the monster, are similar to those of "Alien3".
