There are many such moments in Half-Life: Alyx, but talking about them would feel like a betrayal. It’s a fine idea, but it leads to a reliance on talking about mechanics, maybe a few fights or set pieces that you experience, to give an idea about how the game will make you feel, how the designers have set it all up to tickle the back of your brain. A review would traditionally dance around narrative beats, giving mild details on world-building to set the tone of a game for prospective buyers. It feels almost impossible to talk about Half-Life: Alyx without spoiling something.
