THPS2 added the manual (through which players can link tricks together while moving between physically separated ramps or rails), create-a-Skater, and a park editor where players can create their own levels. THPS3 added the revert (which consists of making a 180° spin as soon as the skater hits the ground after a vert trick/combo), as well as updated graphics for the newer consoles at the time. THPS4 changed the career mode by getting rid of the 2 minute timer, letting one freely skate the level and to perform goals at any time by talking to NPCs. It also added the spine transfer (which allows the player to hit a ramp placed back-to-back with another), and the ability to skitch cars (by grabbing on to their rear bumpers as they move).The fifth game of the series Tony Hawk's Underground, had the game focus more on a storyline. The player can create a skater, and take him or her through a rags-to-riches story that involves them going from amateur to pro, meeting some wacky characters along the way. THUG added the ability to walk off your board, along with driving vehicles, and wallplanting (the skater pushes himself off a wall in mid-air). Create-a-trick, create-a-goal, and create-a-deck were also added. Tony Hawk's Underground 2 continued the story. It involves an event called "World Destruction Tour", in which you join Tony Hawk's team to go around the world and destroy things. The ability to sticker slap (replacing the wallplant), Natas spin (which consists on the skater spinning while keeping his grip on top of structures like poles or fire hydrants), and spray a graffiti tag (which can also be created by the player) were added. The original career mode from the first four games returned under the name of "classic Mode."Tony Hawk's American Wasteland was next. The game took place in one streaming world of Los Angeles, with no loading times. BMX bikes were included. The story revolves around you moving to LA and building a "skate ranch" (a large skate park filled with large skatable items stolen from the city, such as a highway sign and a crane). Tony Hawk's Project 8 made some dramatic changes, such as dropping some abilities to make the game more realistic. The graphics were completely overhauled, pro skaters were now "mo-capped," and there was a new goal system. Instead of different difficulties, they were integrated into how long you grind, manual or air to get to certain levels. Those of which were AM (amateur), pro and sick. The story has you join Tony Hawk's team of the top 8 skaters, hence the name of the title.
