Tony Hawk's American Sk8land, is the first entry in the Tony Hawk's series of video games for the Nintendo DS, and the sixth Tony Hawk video game for the Game Boy Advance.
American Sk8land uses cel shaded visuals and it was developed by Vicarious Visions, the developer of the Game Boy Advance Tony Hawk games. It is also loosely based on its console counterpart, Tony Hawk's American Wasteland. It was released on November 15, 2005 in North America.
The top screen is used to display the main gameplay, while the touch screen displays an overhead map of the area the player is currently skating, as well as icons for easily performing tricks. The touch screen is also used to create Skateboard art. Furthering the use of the DS's functions is the ability to record, with the DS microphone, your own sound clips for use in the game.
Tony Hawk's American Sk8land was the first Nintendo DS game released by a third party to support the Nintendo Wi-Fi Connection, the online service for the Nintendo DS. Players are able to play Trick Attack, Score Challenge, Combo Mambo and The Price is Wrong. Players are also able to upload or download graffiti, board art, highscores, and replays to one of the servers, and can periodically download new goals to complete.
In the DS version, the ability to get off the skateboard and walk around was removed; however, this was somewhat balanced by the ability to come to a complete stop and rotate the camera.
The name is shared by the Game Boy Advance version, also created by Vicarious Visions. The GBA version does not share the same graphics, however, having an isometric point of view, polygonal skaters and pre-rendered levels creating a 3D sensation.
