A video showing a Half-Life fan's efforts in modding Oculus Rift support in to Half-Life 2 has been making waves since it was uploaded to Youtube on Sunday. The video shows Nathan Andrews using an Oculus Rift virtual reality headset and a modified Xbox 360 Top Shot Elite gun controller with a motion tracker taped to it playing Half-Life 2. The results are pretty impressive: The setup allows the player to independently look around using the Rift's head tracking and aim using the motion trackers attached to the gun. It looks like a lot of fun and if you can afford to spend a few hundred dollars on creating the setup yourself you can download the mod from here. Perhaps a company will take noticed and produce similar guns for consumers for when the Rift hits shelves.
