This rail shooter has been getting a somewhat cult classic like buzz on the interwebs so I feel inclined to try it out.

Heres some info on the game:

The game is notable for replacing the typical sound effects found in most rail shooter games with trance music, with sounds and melodies created by the player as they target and destroy foes in the game, leading to a form of synesthesia, enhanced by an optional Trance Vibrator peripheral. Although Rez was critically acclaimed, it did not get much commercial attention in the United States, partly due to its esoteric gameplay experience.

Rez is a rail shooter in which the player takes control of an onscreen avatar travelling along a predetermined path through the computer network. The player cannot affect his or her movement in any way (aside from choosing a few minor branching paths by shooting specific targets in one level). The player targets foes by holding a “lock-on” button while moving an aiming reticule over up to 8 enemies. Once the “lock-on” button is released, the avatar fires shots that home in on each target. Failure to hit an enemy or projectile in time may cause a collision, which reduces the player’s current evolution level by one and changes the avatar’s form. The game is over if the avatar is hit while at its lowest possible level. At higher evolution levels, the avatar appears as a humanoid figure, while it appears as a simple sphere at the lowest level.
