After lowering the submersible and swimming down into it as described in part 1, your next goal is the small opening between the two lights on the wall below the sub. Drop into the water and swim down toward those lights...

...and through the square opening just above and between them.

NOTE: This door remains closed until you place the BATTERY and WINCH STARTER, so it's not possible to use the exposure meter bug to reach the end of the level before collecting those items.

Swim through the opening, then to the right...

...along a short tunnel in the ice and right again.

Just ahead is an opening in the ceiling where you can climb out of the water.

Pick up the large medi pack here.

Make sure your exposure meter and health bar are full before making the last long swim. Jump into the water and head forward into the right corner of the little icy passageway.

Now swim up a long, water-filled shaft. You'll swim through a save/power-up crystal on the way up.

At the top, there's a small ledge on one side where you can climb out of the water...

...and pick up a small medi pack.
