This is a list of mostly in-game glitches, as well as some bugs and a few just plain cool or hard to get to places that can be found in THPS4. This list focuses on the PS2 version of the game and only said to be for a platform if we have actually tried the glitch. Our guess is that most of these also work on X-Box, Game Cube, and PC, but we have not had the opportunity to try. If you do try these out on other platforms let us know the results!
All of these glitches have actually been done by us here are thugXonline. Special thanks to Invisible Man, Jubei, and bens0nn for helping out!
