This game had me so immersed i was diving for cover left and right, saw a combine enemy and dropped to the floor for cover simply out of instinct. This isn't the case of a mid game with excellent immersion because its vr, even if this wasn't a vr game it would be one of my all time favourites. Such amazing attention to detail, the gameplay is amazing and its so immersive you forget you have a miniature cinder block strapped to your forehead.
