Here is a user video from gametrailers that shows the evolution of Heavenly Sword.
Videon from Gametrailers.
Maybe someone from NT can confirm that it contains photo from that build.
Enjoy!
Taking that video from gametrailer, bit by bit...
The first segment was done in Maya all CG. It was the original pre-vis of the game, as you can tell its changed a fair bit from there to the next bit.
Next clip is from the build I mentioned, which would have been showed behind closed doors to various publishers in E3-2004. Its probably the first 'real' Heavenly Sword footage, you can derive lots of things from there to the shipping game.
I can actually run and play that very build today on my PC. It used the best PC money could buy at the time to be playable. Even then it was usual to turn off some of the graphics options (like shadows) if you were demonstrating combat for the extra speed.
There were essentially three environments, the main one is the 'demo' it consists of Nariko fighting multiple waves of enemies in an arena with some dialog and anims to set the action. This has descended directly down through the E3-2006 playable and into the game as the CH2 'Banquet Hall' fight, which finishes with the first Flying Fox fight.
Also there was a walkable section which had no gameplay but showed off the vistas. This section (the level would forever be known as "walkways" inside NT but technically was called the water temple) would become CH2.
There was also a boid-AI system driving lots of guys, the first approach to the army sections.
The next segment is E3-2005 which we frame-captured from the game at that point and used in the PS3 launch. I posted on here back when it was first shown with details.
Next clip is E3-2007 which is of course, pretty much what shipped.
That montage is missing the E3-2006 trailer but that's because that E3 was dominated by first playable.
