3rd Logo (March 2, 2012)
Logo: We see the same hat as before, though in other view and only the silhouette. The name below is designed in the usual way, but uses another font.

Variant: On the trailer for Project X, the logo appears on the dirty green background with stains, and a shiny gold-metallic appearance on the hat.

Technique: None. This was done by Prologue. According to them, the film's goal was to create a simple low budget look and type to coincide with the idea that the film was created through the use of a home movie camera.
