Half-Life: Opposing Force Hints
How do I get to the sewage overflow controls?
1 of 12: Have you read the signs? They specifically say "No Access During Robotic Loader Operation."
2 of 12: Hence, as long as the robot loader is present, you do not have access to the ground floor.
3 of 12: Unfortunately, the robot seems to be having some trouble. Maybe you should help it out.
4 of 12: The robot cannot fully pivot, as it is being blocked by some crates.
5 of 12: Some of those crates are explosive.
6 of 12: Plug a few rounds into one of the explosive boxes to free the trapped robot.
7 of 12: Once the robot is free, it will proceed to set the box it is holding in the middle of the radioactive sludge and then leave the premises.
8 of 12: Once it is gone, the bars preventing you from using the ladders will be removed and you can then move down to the ground floor.
9 of 12: The ground floor is flooded with radioactive sludge. Be sure to climb down the ladder that is directly above some boxes.
10 of 12: Hop across the boxes and over to the sewage overflow controls.
11 of 12: Push the button to drain the room of most of its radioactive sludge.
