  2. From the previous secret, continue going up the steps. You may notice that one of the brown steps leading up looks different. When you cross this step, a door opens for a few seconds. To reach this door, from that step, keep going up, and at the fork, go west and around to the opening here. Take the lift down to enter the nukage room, where the switch behind the pillar will lower the chainsaw. (sector 82)
