Next Tuesday North Americans will be able to get their hands on Silent Hill Shattered Memories which is the third and last survival horror game this year for the Wii. The earlier two being Cursed Mountain and Juon the grudge.
If you are planning on picking up the PlayStation 2 or PSP version you will have to wait until a later date which Konami has yet to announce.
It definitely looks like the most impressive of the bunch. I plan to check it out some day, but I say that about a lot of games.
