Rez HD

Rez HD is a rail shooter/music video game for the Xbox 360 video game console, one of several downloadable games found within the Xbox Live Arcade. Based entirely on Rez, a game developed by United Game Artists and released by Sega for the PlayStation 2 and Dreamcast consoles, Rez HD's main changes to the game are improved graphics and enhanced sound. The game is notable for replacing the sound effects typically found in similar shooting games with trance music that changes in relation to the actions of the player.

Since a large part of the appeal of Rez comes from its unique music, a special peripheral called the Trance Vibrator was produced and released only in Japan, exclusively as part of a special edition of Rez for PlayStation 2. The USB device vibrates in time with the music much in the way the rumble pack in the controller does. Intended to enhance the richness of the player's immersion into the game, reports unsurprisingly claim that some had used it for sexual purposes. The device is not compatible with the Xbox 360, and no plans to create a Trance Vibrator for Rez HD have been announced.
