Narcosis is a game of many hats. Survival, horror, stealth, all intertwined as you embark the depths of the ocean in a dive suit, to solve what has happened to your fellow dive crew. One of the things I like most about this game is the feeling of being in the suit. The top of the suit has a dome “glass bowl” type helmet that you look out of. On the lower portion of the helmet area is your HUD. The HUD displays your current oxygen level, thrust usage, and a few other details. The HUD also has a slight reflection off of the glass interior of the helmet that feels quite realistic Although the game doesn't have tracked motion controllers,  the sense of immersion is there due to the built-in claustrophobic nature of the dive suit. . If you're a fan of the genre it's certainly worth checking out.
