Enemy Zero

Enemy Zero was the second game to star the digital character Laura Lewis—the first being D.

In E0, gameplay sequences alternate between interactive FMV and real time exploration, both from a first person perspective. The interactive FMV component uses gameplay identical to an earlier Warp game, D.

The real time component of E0 is unique. Enemies are invisible, and location is only possible through the use of sound, with notes of different pitch helping the player find the distance and direction of enemies.
