With a recent leak found in a Dota 2 patch, there are tell tale signs that a VR Half Life experience may be in the works, seemingly not starring Gordon Freeman (as you can actually talk this time), this is an exciting prospect as Valve very rarely disappoint. Yet knowing Valve like we do, it'll probably be a long time til we hear anything about this but we will update as soon as we find out more.
Half Life VR has been added to Game-Debate but does not currently have the Half Life VR system requirements. If the game is less than 3 years old and you know what the system requirements are then please send them through to Felix and we will get them updated. Where possible, also send a link to the source of the system requirements to help us validate the information.
