Gentlemen, we can rebuild it. We have the capability to make the world's first enhanced store. Steam will be that store. Better than it was before.

I just finished a few hours of playing Submerged, which is 66% off ($6.79) right now which matches it's current historical low price (although it's $3.99 on sale on PSN for + members, which is where I bought it.)
The game focuses on exploration and storytelling rather than combat or action. In a way, it's really relaxing as you take your boat out over a long lost forgotten sunken city which happens to be the ruins of a modern day metropolis. Your job is to gather supplies to aid your wounded younger brother. The focus on exploration here really shines, and the graphics are pretty nice too with some great water and lighting effects.
As you progress through the story, you're given a series of pictograms that tell the story of what happened to the city, and also tell the story of how you got there to begin with and what happened to your brother. There is some voice acting but it's all in a strange made up language, so a lot of the story telling is done through pictures and body language.
You can find and pick up boat upgrades as well as story pieces, and you get a telescope which you can use to look for supplies and also watch the local wildlife. Once you find the supplies you can dock your boat and gather them up by climbing ledges, vines, ladders, gutters, etc.
It's pretty short probably around 3 hours (more if you want to gather up all the things) but it's a nice little game you should keep an eye on if you're a fan of story-heavy exploration games.
