I beat the game but here are some things I was wondering about
- I couldn't seem to find the control module for the aliens I found the power core, but that's it
- what do we do with the key on the floor of the diamond mine?
- I found the password for the door keeper in the hangout, but he wants a hat.. can we find him a hat?
- what do we do with the purple tapestry in the castle with the cult's mark on it? I tried wearing the blood amulet but nothing worked.
- What do I do with the letter I get after witnessing the wedding-gone-wrong? I tried giving it to people to no avail..
- outside the castle, if you go toward your car, there is a wall on your right which looks like it has a hidden passageway inside. Any idea on this? Can we get inside there?
- what's the deal with the wolf? I got the picture, i shot the wolf, I met the door greeter guy.. and thats it. After I beat the game, I tried to go and refill the gas tank of the car but it wont let me.
- where do I use the overstock supply key?

I figured out the bolts and the blue chest from other posts, thanks!!
