Attempts to climb are slow, and the heavy suit only makes it harder. However, you are still able to make steady progress. Looking around as you climb, you notice little eyes in the darkness watching you. You decide to ignore them and focus on climbing. After a while you hear water rushing and feel a great smack in your side as one of them crashed into you, knocking you off the side of the drop off. You tumble back to the sand and look up to face your attacker. None can be seen. You peer into the dark abyss and see naught but the eyes just out of any real view staring back at you. You resume your climbing, but now watching more intently around you in case of another attack. Your lights seem to keep them away, but they are dimming. You are losing power. You barely make it to the top as your lights run out... From there, what happens is only between me and a future developer =P

You look around. Surely climbing up that drop off would be difficult, since it's almost pure sand. Maybe you can find a better climbing surface? Or perhaps a part of the drop off that is less steep and more accommodating to your heavy suit? You traverse the floor, moving between rocks and undersea foliage. Things are strangely quiet, and there is a lack of life. Then, you start to see eyes in the darkness. Not close enough to discern any real details about their owners, but their eyes definitely reflect in your light. You press on, however, undeterred. Probably nothing to worry about. You have to get out of here. You keep following the wall until you come across a large stone column in the middle of the ocean. Peculiar. You look closer at it and see strange carvings of an ancient civilization. Intrigued, you press on to just barely see a structure in the distance... The eyes are drawing nearer, though, and your lights are dimming. They seem to close in more and more as the lights dim. What happens next is between me and a future developer =P
