In years past, Konami has hosted their own press event for E3, which the platform on which they unveil the Castlevanias and Metal Gear Solids of the world. This year though, they've opted to host their event the week before the E3. and they were even nice enough to include a video detailing all of their announcements and the upcoming slate of games.

The hour-long epic includes appearances by Hideo Kojima, 8-4's Mark MacDonald and even Mega64, and details upcoming releases such as Silent Hill Downpour and the newly-confirmed Metal Gear Solid HD Collection.

Metal Gear Solid Snake Eater 3D

From what amounted to an interactive video at E3 2010, Metal Gear Solid Snake Eater 3D is now a fully-fledged port for the Nintendo 3DS. Konami kicked off their press event with a video featuring some familiar scenes from the PS2 original's intro, as well as the new features that will be included with the port.

Using the accelerometer, Snake will now be in danger of falling from a tree or a bridge if the 3DS is wiggled too much, adding an additional element of danger to the traversal challenges. The camera, meanwhile, will be used to augment the existing camouflage system. If you snap a picture of a flower, for instance, the colors can then be applied to Snake's camo. Doesn't seem particularly worthwhile to make Snake a very unstealthy shade of pink, but it'll at least be good for a laugh.

And in what has become a tradition for Metal Gear Solid, the new Snake Eater 3D offers a tip of its cap to its new platform at the end of the trailer. Seems like we should expect plenty of Easter eggs when it arrives later this year.

Pro Evolution Soccer 2012

Konami detailed some of the changes that will be coming to Pro Evolution Soccer 2012, which mainly seem to encompass mechanical changes and artificial intelligence upgrades. In particular, they'll be focusing on off the ball movement, ensuring that teammates provide support even when they aren't directly involved in the action. The mechanics are also being streamlined to add more depth to the one-on-one dribbling that is integral to evading opponents and moving the ball up the field. FC Barcelona forward Lionel Messi drops by at the end of the presentation to offer his thanks to PES fans and best wishes to Argentina in the upcoming Copa America cup.

Zone of Enders, Silent Hill and Metal Gear Solid HD Collections

Amid the mess of trailers, Konami announced HD collections for Zone of Enders, Silent Hill and Metal Gear Solid. Confirming speculation, the Metal Gear Solid collection will include an updated version of Peace Walker in addition to Metal Gear Solid 2 and Metal Gear Solid 3, and will be "optimized and completely rebuilt specifically for Xbox 360 and PS3." That means a high-definition user interface, as well as redesigned controls that make use of the right analog stick and force feedback.

Information on the Zone of the Enders collection was a little more sparse, but both games will be given the same treatment as the MGS collection. It's due in 2012, while the Metal Gear Solid updates will be released in November 2011. The Silent Hill Collection, meanwhile, will feature the second and third entries "retouched in high-definition," but Konami did not divulge any further details.

In an interesting twist, those who have completed Metal Gear Solid Peace Walker won't necessarily have to start from scratch with the HD version. That's thanks to a feature called "Transfarring," which Hideo Kojima says is being introduced as part of what he envisions as the "new mobile gaming lifestyle."

Transfarring

Mega64 was on-hand to introduce transfarring in a skit that riffs on the classic Star Fox 64 promotional video released back in 1996. In simple terms, it will make it possible to transfer a PS3 save file to its PSP counterpart, and back again. So if you happen to own both the PSP and HD versions of Peace Walker, it will be possible to save your progress in the living room and pick up again on the bus.

Hideo Kojima called the Peace Walker compatibility "Step 1" for Transfarring. Step 2 will bring "PS2 class games" to the PS3 and NGP, with Transfarring being possible between the PS3 and NGP. In its final phase, Kojima says Transfarring will make it possible to transfer data from a PS3 game to the NGP.

Under this new system, it will be possible to play PS3 games pretty much anywhere provided that you own an NGP. It's not clear at the moment whether you will need to own both a PS3 and NGP version for it to work, but it's certainly a possibility. The Zone of the Enders Collection will be Transfarring-enabled, so that ought to give us a glimpse of what to expect on that front when it arrives in 2012.
