It didn't take very long. In just five days, Half-Life: Alyx has become playable without a VR headset and with mouse and keyboard controls.

The first Half-Life: Alyx is still very rough around the edges, as it uses Half-Life 2 models for weapons and jumping doesn't work properly. Still, this is a great way for those without a VR headset to enjoy the first entry in the series in a very long time.
