Kojima-san has announced on Kojiblog that the new MGS Peace Walker demo will hit this coming Sunday - November 1st.
The new demo will feature a third new control scheme that came about after feedback from players at TGS. The demo is basically a revised version of the TGS show floor demo which wasn't distributed. The demo will be offered through PlayStation Network, the Peace Walker official site, and various other web sites simultaneously.
This new demo should be considerably better, Kojima-san has revealed that the first demo we got was made way before TGS, meaning this new demo will be a better reflection of the game fans will play in the retail release.
The demo will be feature a new stage and the ability to control the camera during the game's cut scenes, improved enemy A.I & behaviour patterns, as well as changes to the CQC system. It will also have a fourth wallpaper.
