"Tony Hawk's Pro Skater 2" and "Spider-Man" were both released in 2000. Neversoft began work on "Tony Hawk's Pro Skater 3" specifically for the PlayStation 2. After both teams finished their projects they were merged into one large team. "THPS3" was developed using the RenderWare game engine. "Tony Hawk's Pro Skater 3" was released in 2001, followed by "Tony Hawk's Pro Skater 4" in 2002. In 2003 Neversoft reworked the game with a more story-oriented approach in "Tony Hawk's Underground", followed by a sequel in "Tony Hawk's Underground 2" in 2004. In 2005 Neversoft again split into two teams to begin work on the internally developed "Gun" and the seventh version of the "Tony Hawk's" series — "Tony Hawk's American Wasteland".
