John Carmack left poses with Oculus founder Palmer Luckey center and other members of the Oculus team.

The 2014 lawsuit filed against virtual reality headset company Oculus and its parent company Facebook has now received its first major amendment in nearly two years.

The civil complaint from game publisher ZeniMax was updated on August 16 with 22 additional "paragraphs," and those updates mince few words.

Most notably, the lawsuit now names Oculus executives John Carmack and Brendan Iribe as defendants, in addition to the aforementioned companies and Oculus founder Palmer Luckey.

The updated filing, which was reported by Game Informer on Monday, still alleges that Oculus's major VR technologies were taken from ZeniMax in a way that violated contracts and nondisclosure agreements—especially since Carmack originally worked for ZeniMax and had signed contracts that made ZeniMax the owner of any technologies he worked on within the company specifically, at its subsidiary, id Software .

Now that Iribe and Carmack are listed as defendants, ZeniMax has aimed further allegations directly at those two men—and have questioned claims that Luckey had much to do with the development of Oculus' core technologies.
