Description
Near the end of Chapter 18, after you have been freed of a mind controlling bug, go back onto the conveyor belt, and push one of the boxes right to slow it down, then as the crusher on the left is moving downwards, jump on the box and jump across to grab onto the crusher, wait until it goes up, then as it begins to come back down, climb up and run across it, as you come to the end, wait until it starts to move upwards again, and then jump left and grab onto the ladder. Climb up and run right, walk under the cog, making sure not to get crushed – and walk over the blob for the achievemenet.
