Flipping the switch will close the door behind you, and open the door in front of you. You need to light up both these panels before you can activate the flush control, but you've got some hoops to jump through first. In the middle of the room is a panel marked 'Flush Toxic Waste', and two switches labeled (appropriately enough) 'Gearbox' and 'Valve'. Back under the broken ramp you'll find some crates and a small vent opening.Ĭlimb in the vent and you'll emerge at a small control room overlooking the Pit Worm. Take out the aliens you find there and round the bend to a broken ramp and another alien. When you have an opening, jump down to the first ledge and to the right.
When you first open the door, try and distract the Worm by shooting him in the eye, which will stun him briefly.
