I have read a lot of this game, unfortunately it is VR-only game.
I think that this is the first game that implements a serious approach to the VR-style, but we can also say that this is a master economic move: Valve released its own VR headset called Index and they are using Half Life hype to boost the sales.
I am a bit curious of how it will end: to play VR games like that you need both powerful pc, VR headset and a dedicated room with enough space, the final cost is likely over 2000€, a very small number of people can afford such thing.
@"Hidden Refuge" On the web there is a proof video of a hidden feature of Half Life Alyx that enable a "fake first person shooter view" but the game is still unplayable.
