In Cassie Cage's Selfie Fatality, after she posts the picture she takes on a social network, the website contains a few references:

• The trending section has the headline "KILLING SPREE: Masked killer stalks campgrounds". This is a reference to Jason Voorhees from Friday the 13th, who is a downloadable character.
• An ad below the trending section has Johnny Cage starring in Ninja Mime. The movie was previously advertised in Mortal Kombat (2011), where ads of it are found in the Subway, Rooftop, and Street levels.
• The community list at the left lists all the organizations available in the Factions mode.
