Alyx pushes the limits of current VR game design in various ways. The writing and world-building are as good as any other Half-Life installment, which is to say that your mileage may vary. However, when it comes to gameplay and visual design, no other VR game can touch Alyx. Set as a prequel to Half-Life 2, you play Alyx Vance, exploring the mysteries of an Earth conquered by alien beings after a disastrous physics experiment we first saw in Half-Life 1.
