-- 2003 (US)
This disc was a pre-order bonus from Gamestop (I believe?) for reserving .hack//Mutation. Unfortunately there isn't much new to it over the one for Infection. The main menu screen is new. It uses background Image 67 from the games and the following options available are:
.hack//Infection Part 1 - Playable Demo
.hack//Mutation Part 2 - Trailer
.hack//Outbreak Part 3 - Coming Soon
.hack//Quarantine Part 4 - Coming Soon
That's right, the demo is for Infection again, not Mutation. And it's exactly the same demo to boot. The trailer at least covers Mutation and Liminality 2. That doesn't make it any less disappointing that there isn't a demo specifically for Mutation however, especially since I bet if I looked, I'd find the same trailer on one of the SIGN discs. Not much reason to hunt down this disc other than for collection purposes.
