The control room puzzle solution – Resident evil remastered

The control room is located at the bottom of the Aqua ring near the area full of water with sharks. Use the control room key to get inside the control room.

Go to the control panel downstairs and press on the water drain switch. It's located where the panel displays the word 'error' in red.

As soon as you press the switch, an emergency alarm will fire. You will have to continue the rest of the puzzle fast. Press the safety mechanism switch which lies on the same panel.

Next, you need to find the lever to pull in the control panel. It's near the other switches you pressed. Pull the lever when you find it. The mechanism will fail, don't worry.

Go back to the area in the room where there are large tanks and press on the switch #1.

Go back to the control panel and shut the safety off again.

After shutting down the safety you need to pull the lever one final time. This time the glass windows will be barricaded.

Now press on the switch that drains the water and it will work. When the water gets drained, it will open the path to previously blocked areas.
