I have turned on the power in the Power room and made my way to the gate with the keypad. I have to kill the dog behind the gate. After being unsuccessful in direct combat, I decided to drag a crate to jump up on after opening the gate. Maybe that's not what you're supposed to do, because if I'm up on the crate, the dog gets stuck behind the boom and the game just "glitches" and it won't move. Anyone else tried this method to stay alive while trying to kill the dog? If I jump off the crate, the game continues. Why can't I use a crate to stand on?
