Rez - PlayStation 2

But problems begin when Eden becomes self-aware and suffers a breakdown. You must take control of the network while you manically search for Eden to bring it back online. The network was built to keep intruders out at all costs, so you'll have to fight off enemies from all sides. To reach the system's core, you'll need to shoot your way through each area and take out its specific firewall (boss) to wipe out that part of the system. By hacking the system, you'll alter the visual output and even take over the music, creating your own rhythms and eye candy as you dig deeper into the dreamlike cyberworld.
