The Geek Link writes- Back in 2001, Konami released Zone of the Enders on the PS2. While a fun and unique game, many people bought ZOE for another reason. Konami had a playable demo of Metal Gear Solid 2: Sons of Liberty, a highly anticipated sequel, available to those who bought Zone of the Enders. With the release of Zone of the Enders HD Collection, it seems that Konami is content to have history repeat itself, as gamers who purchase the Zone of the Enders HD Collection will be able to install and play a demo for the upcoming Metal Gear Rising: Revengeance. At its core, the demo shows off some very fun mechanics, along with a few concerns that are hopefully addressed.
