Iron Lung

Very simple and basic Horror game. You control a submarine through a bloody ocean with only using a map and some co-ordinates/angles you can adjust the sub with. The game's objectives gives you 10 nodes on the map to explore. Reach the exact co-ordinates and take a picture and you'll progress. The map has caverns you have to carefully explore without hitting the walls. I played it because of Markiplier's upcoming movie based on this video game.
