CLAM SHAM!
The secret is called "Clam Sham," Oyster*****. I know that doesn't make any sense, but hey, I found it out myself and I'm not going to spoil it!
Great game, seems like a old horror setting, but it's still not. That's awesome..
I mean it's scary but it's not scary. Aahhh, play and you'll know what I mean.
