Konami of Europe today unveiled further information on three new Kojima Production titles being displayed at the Tokyo Game Show for the first time.

A new Konami development force, Kojima Productions is named after and headed up by Hideo Kojima, creator of the Metal Gear Solid and Boktai series. The team is using the September 16th-18th event to show the first footage of the already eagerly awaited Metal Gear Solid 4 (Working Title) for PlayStation 3, and new additions to the forthcoming Metal Gear Solid 3: Subsistence for PlayStation 2 and Metal Gear Acid 2 for Sony's PSPTM (PlayStation®Portable).

Metal Gear Solid 4:

Following Kojima's comments that the fourth Metal Gear would be set after the events of Sons of Liberty, he is using TGS to show a nine-minute trailer featuring the first actual game footage from the PlayStation 3 title. Metal Gear Solid 4 sees Kojima Productions taking on the task of 'creating inner qualities.'

"The inner aspect is unseen and establishes the presence only through time and the volition of the player," explains Kojima. "This will pave the way forward to a revolutionary change that will lead us away from past concepts based on 'realism' as we move towards the 'natural'."

For the new game, series hero Solid Snake moves into a battlefield scenario, which will bring many new challenges in the harshest of infiltration missions. The drama and chaos of the battlefield, as well as questions of who to trust in war, will set the scene for a new era in the Metal Gear Solid series.
