Half-Life: Deep Maroon mod

Explore the deep sea nicknamed "the Deep Maroon" on a giant Xenian rock nicknamed "PeOk", inside an old steampunk styled submarine. If you've heard of "Iron Lung", then you would already have a basic idea of this mod.

Traverse your submarine through the sea, in search of a very delicate specimen. You control your submarine using three different levers with two possible actions each; Move forward/backward, traverse left/right, and ascend/descend. Use the computer to capture images outside in front of your submarine, because that's the only effective way to help your awareness of your surroundings. Try not to crash into walls, because you may definitely find yourself within crevices, caverns, and even in front of something that moves and/or makes a noise. Be sure to always capture your surroundings for an interesting discovery.

Besides the camera, you can hear almost anything nearby you come across and you can use your collision detection monitor, and coordinate system *along with your map of the sea area you'll explore for better coordination.

*Set in the mid-twentieth century, during one of the first Black Mesa teleportation technologies and the first survey teams, Scientists have come across an enormous moon-like rock with twenty percent of it being a sea. The water seems to be very identical to the healing pools, but has extremely low healing values, almost effective as a plaster. It is unknown whether you're the first group of Survey Teams to explore the moon, since there's an established base and dock right at the shore, with things up and running already.
