Unlocking every Secret Skater in Tony Hawk's Pro Skater 3 + 4 can pose a challenge for perfection-seeking players.
Most Secret Skaters can be bought from the Secret Shop accessible from the main menu, eliminating the need for difficult tricks to unlock them.
There are five Secret Skaters in total, each with a price tag attached in the Secret Shop or specific challenges to unlock them.
While unlocking these characters doesn't offer significant benefits, they bring unique special tricks adding flair to gameplay, especially in photo mode.
