Your'e not doing it right. (Starting from the beggining of the sector) Youv'e got to continue going left until you reach a room where there's electrified water below you, a passage above you and a door to the left. Go up. Continue upwards until you reach a door to your'e right. Enter, and you will be able to save. Now look to your'e right. There should be a cracked block on the right side of the save station. Shoot it, and pass through it. Continue going right. You should pass a large room with a big skeleton in a tank of water. Get rid of that big eye whosamadingydong and pass into the next room. (you should be underwater) Jump onto the ladder to your'e upper-left and run across the pathway. Serris should appear at a high speed. Hope this helps you. Good luck!
