How to install THUGPro

How to install THUGPro:

THUGPro is a total conversion mod for Tony Hawk's Underground 2 that ports many of the levels from THPS3, THPS4, THUG, THAW, Project 8, and remakes of levels from the first two games that were originally unlockable in the later games. It also has a bunch of characters added including secret and guest/bonus characters from games other than THUG2.

Getting THUG2:
Download the archived copy of the game from Archive.org and install it. Do NOT install it under Program Files, install it in a folder called "PC Games" or something instead. There should be a CD Key text file to reference when it asks you for a key. After you install it, you're free to play THUG2 as it is or continue following this guide.
