Supposed Black Ops 2 in-engine screenshots have appeared online, via the special effects firm that helped create the Quadrotor viral video from earlier this week.
The images, which were released - and quickly pulled - by mechanical special effects company Reel EFX, show the Quadrotor device "in-game".
Activision previously posted a teaser image on Call of Duty.com showing the futuristic attack drone, which suggests the new Call of Duty will adopt a near-future setting.
"The technology in this baby isn't going to be out there for at least another decade," the presenter of Activision's viral video said of the drone. "Looks like the future's going to be fun. But if you can't wait another 15 years my friends are telling me that this baby might just be in the next Call of Duty game, which would be the shit."
The next Call of Duty game is due to be unveiled on May 1 and is widely tipped to be Black Ops 2.
