Tony Hawk's Pro Skater 2x was released as a launch title for the Xbox. It arrived in North America on November 15, 2001, the same day Microsoft's first game console reached the market.
The game was an Xbox-exclusive re-release combining content from Tony Hawk's Pro Skater and Tony Hawk's Pro Skater 2. It included the original games' levels, five additional stages, and selected features associated with the then-newer Tony Hawk's Pro Skater 3.
A common mix-up is assuming the “2x” refers to a conventional sequel released across several systems. Instead, it was designed specifically for Xbox and took advantage of that console's hardware with improved visuals, larger environments, and smoother animation. The PlayStation 2, GameCube, and Dreamcast were not its launch platforms.
