Kelly Slater's Pro Surfer (known as: Kelly Slater Pro Surfer 2003 in Japan) is a extreme sports video game in the Activision O2 brand. It was developed by Treyarch and published by Activision in 2002 for the Nintendo GameCube, PlayStation 2, Xbox and Game Boy Advance. In 2003, it was published for Microsoft Windows and Apple Macintosh. Capcom has published and released a Japanese version of the PlayStation 2 version on May 17, 2004.
This game has a trick system which is in many ways similar to the one used in the Tony Hawk's Pro Skater series; however, as surfing is a rather different sport than skateboarding, the actual gameplay similarities are limited.
