In Tony Hawk's Underground 2: Remix, on the Santa Cruz stage exclusive to that version, if you travel out-of-bounds behind a wall near the Amusement Park/Arcade area, you can find a hidden picture of a distorted red face.

Within the debug menu of T.H.U.G 2, there is an option to instantly grant the player a score of five million points.
When this debug function is activated, the text near the bottom of the screen in which the name of a trick performed during a combo would appear, instead the phrase, "You cheat like Kurt" fills in.
References to "Kurt" are a running inside joke within Neversoft, with numerous respective instances occurring in both Tony Hawk's Underground 1 as well as Underground 2 as Easter Eggs.

Accessing the arcade cabinet used for a specific goal on the Skatetopia level reveals a hidden message written out in the high score initials.
The message, reading, "TEN HARDCORE YEARS KICKING YOUR ASS", which is a reference to Neversoft Studios developing the Tony Hawk game franchise for ten years.
