"This is the latest prototype," the Oculus guys tell us. That's great, now strap us in. The team decided to make a sudden stop in Germany ahead of appearances back in the US over the next few weeks -- and we're glad, because it meant we got to call in on them and grab some time with the Oculus Rift. If you didn't know, the Rift is a Kickstarter-funded VR gaming headset (stay with us) that's caught the attention of several games developers -- most notably John Carmack. He liked it so much, in fact, that he developed a special Rift-ready version of Doom 3 for the headset and Doom 4 will also be heading to the VR peripheral too. We got to play with the earlier game and while there's a video after the break, we reckon you'll really need to try this in person to fully grasp how the Oculus Rift plays. Check out our impressions after the break.
