One of the coolest parts of the old Tony Hawk's Pro Skater games were the secret unlockable characters. While there's nothing too crazy like Darth Maul or Spider-Man in this remake, we can show you how to unlock the alien to really tug at your nostalgia.

Secret characters are basically a lost art in games today, with the rise of DLC and paid additions taking their place for the most part, but that's not the case with Tony Hawk's Pro Skater 1 + 2. While there are only two secret characters to unlock, both of them are awesome rewards for fully exploring the game world. Of the two, the alien is certainly the more difficult to unlock. If you want to see your skater pull of some truly out-of-this-world stunts, you'll definitely want to check out our guide on how to unlock the alien.

How To Unlock The Alien In Tony Hawk's Pro Skater 1 + 2

Unlocking the alien is tied to a series of collectibles hidden very well among the stages in Tony Hawk's Pro Skater 1 + 2. There are 19 alien dolls you'll need to collect, each on their own level. Because some can be difficult to reach, upgrading your speed and ollie stats will help a lot in reaching them.
