The only really deafening moment of shat bricks had to be during my first COMPLETED run of Justine. I had got to the officer part and died a few time, fusturated, I booted up the game at my friends house before I had to run to work and looked up a walkthrough. In the guide it said "Get ready, once you insert that handle, a monster will spawn and you will be chased. Bricks will be shat."
Nevertheless, I shat bricks SO hard during that chase sequence to the point that I wanted to turn off the game and uninstall Amnesia and NEVER look back. My friend was watching me scream and whimper and I nearly knocked over some stuff on his table. My entire body was shaking and since I had one elbow on the table, so was the entire table. My friend asked "[Optimus], are you ok dude, do I need to take you to the emergency room?"
I was speechless for the rest of the Justine run and on my way to work. Even barely talking and shaking for another two hours.
I still have yet to finish the main game and if Justine made me shit bricks that hard, then I am not looking forward to the next few areas I have left.
And yet I will do it for the rush alone.
