Half-Life Alyx may have launched only about three weeks ago, but the Valve game already spawned a veritable plethora of mods as we all expected. The most anticipated one was, of course, the one that lets non-VR players experience the game without having to use a Virtual Reality headset.

However, those who actually plan to play using VR can rejoice with the 'XenThug' mod, created by 'Manello'. This mod adds what is a rather simple, yet potentially fun horde defense mode.
