upon following the footprints, u will eventualy see handprints...follow them 2 find the teams hand prints with there signiture next to them further on.
Also, in Act 2, when following the footprints, I came across a crop circle and a vocal flashback of Campbell saying "I was driving home. I had a couple of miles to go--I looked up and saw a glowing orange object in the sky,to the east! It was moving very irregularly...suddenly there was intense light all around me"
in act 1 in the very beginning the statues when you blend in with it you grab its penis and if you let go and go back to blending in with the statue it falls off..
if you call Rose on the codec and shake your controller, her boobs will move lol
in act 3 you are not the only one doing the following..
