The Oculus Rift virtual reality headset has surpassed its $250,000 goal with 4,581 backers pledging $1,121,315 and it still has 28 days to go.
The Kickstarter was born on Wednesday, August 1, and in less than 24 hours met its funding and then some.
"It's going to be a fully supported feature on [DOOM4], because I think I could justify — based on the response that we got from our 8-year-old re-release title on here, when we finally do end up giving demos on DOOM 4, we're gonna say, 'Okay, here's all this great stuff, run through all this stuff,' everybody has a great time, and then at the end you can play it in virtual reality, and that'll just put the stamp on everything.
"So I think I have good justification for my continued involvement in it."
Carmack said during Quake yesterday DOOM 4 would be "done when it's done."
