I read on Wikipedia that in the game, it's revealed that Walter Peck at one point was possessed by Ivo Shandor; was that supposed to be a reference to his actions in the first movie, or was he possessed by him in the game?

Peck was possessed briefly in the game, but it was by a simple possessor ghost at the museum.

At one point in the story the guys think Peck is drawing power from the Mandala, but it turns out to be the new Mayor, who is possessed by Shandor.

Haven´t you finished the game yet??

My room-mate and I have it for the Wii, but we don't really get to it that often; we have lives, y'know!

I'm planning on eventually buying an XBox 360, and getting it for that…I'm not too fond of the Wii controls.

the reason I asked about Peck was due to the fact that his action figure is being released this March.

Good…so now I won't desire having a 2nd Walter Peck figure to keep carded; I'll just get one…for the containment unit.
