Rez

Rez is fast-action shooter that takes you deep into the world's computer network. The "Project K" Network has recently been upgraded to handle the rapid expansion of the information age and the core, known as "Eden," holds the most advanced artificial intelligence the world has ever seen. Unfortunately, Eden cannot handle the ability to create her own thoughts and buckles under the pressure in an existential breakdown. She is lost deep inside the system, and you're the only one that can bring her back online, saving the world from utter chaos. [Sega]
