SOMA is a horror game and here is the Debut Gameplay! The game will be released in 2015, so it is very far from here.
The first impressions are very good: you can interact with the world in many ways. The style of these interaction are true for a horror game and these new things make the game more scary. We can hear the main character not just breathing, but saying something for these weird things.
The last part of this video we can see a brain cutting apart by some very strange machines.
The era of the game and the feelings are very scary and it is because of the great music and sounds. It will be truly an interestion game with all-new features and it can change pretty much the future horror genre video games.
