Like games of old, Tony Hawk’s Pro Skater 1 + 2 has a number of cheats that you can enable.
Unfortunately, to enable cheats in Tony Hawk’s Pro Skater 1 + 2 you can’t just press a sequence of buttons like you could back in the day. Instead, you’ve got to work for them; you’ve got to unlock them.
To unlock cheats, you need to complete all of the objectives in the game’s levels. Upon completing all of the objectives in the Tony Hawk’s Pro Skater levels you’ll unlock the ability to play with tiny and huge skaters. Complete all of the objectives in the Tony Hawk’s Pro Skater 2 levels and you’ll unlock even more, such as the ability to double the base score, enable super stats, and more.
Once you’ve unlocked cheats, you need to enable them. To do that, from the main menu, go to the hub tab with the left shoulder button. From there, go to game options, then select game mods. You’ll find all the cheats you’ve unlocked there, and can enable and disable them as you please. Just be aware that you won’t be able to use them in all modes, and they may prevent you from uploading your scores to leaderboards.
