Andrews is apparently not keen to wait for Valve to talk about modifying Team Fortress 2 for virtual reality at GDC next month, so he’s started in on his own modding project for Half Life 2 and the Oculus Rift.
Using two Hillcrest trackers, a modified Sony HMZ-T1, and the Top Shot Elite gun-controller, Andrews hacked together a mod to decouple aiming and looking. He says that it also works with episodes 1 and 2 (expansions for the game), as well as other mods and maps.
Andrews stresses that the mod is still early work, but you can find a link to download it and track it’s progress over at his thread on the MTBS3D forums.
It’s amazing to see, even without playing yourself, how natural the player’s movements in the game look compared to traditional aiming schemes. If we’re lucky, Valve will soon be releasing an official implementation for the Oculus Rift / virtual reality for Team Fortress 2, and hopefully that’ll extend to the Half Life series as well.
