Sony has asked the courts for a preliminary injunction against Light of Motiram maker Tencent to stop the Chinese megacorp from commencing pre-release promotion of the upcoming adventure game, filing its opposition to Tencent's motion to dismiss the high-profile copyright lawsuit.

It comes after Sony accused Tencent of developing a "knock-off game [of Horizon Zero Dawn] so blatant that the public loudly decried the obvious and pervasive copying of Horizon’s protected elements," claiming the release of Light of Motiram "jeopardizes Horizon's continued success, including current expansion plans for the franchise."

Sony claimed Tencent's upcoming game Light of Motiram was nothing more than a "slavish clone" of Horizon Zero Dawn, and filed a copyright lawsuit in a California court at the end of July, outlining numerous similarities and comparing various marketing screenshots from both games, as well as their descriptions. As we explained at the time, just like Horizon, Light of Motiram takes place in a post-apocalyptic world overrun by giant robot dinosaurs who roam large, natural environments such as tropical forests, deserts, and snowy mountains. Both games even feature red-haired women protagonists that wear very similar outfits and styles, and devices similar to Aloy's "Focus" earpiece.

Just days after Sony filed its lawsuit alleging the upcoming game was a "slavish clone" of Horizon, Tencent quietly updated its Light of Motiram Steam page and swapped out a number of screenshots, including its cover image, before responding to Sony's lawsuit by claiming it was only making use of "well-trodden" tropes and suggesting the PlayStation maker's own game was too similar to Enslaved: Odyssey to the West.

Tencent then hit back by describing Sony's lawsuit an overreach, highlighting other game franchises with similar elements to Horizon Zero Dawn such as The Legend of Zelda and Far Cry. It was "startling," Tencent said, that Sony was now attempting to claim Horizon's concept was original, rather than an idea based on "ubiquitous genre ingredients."

Now, as reported by The Game Post, Sony has dismissed Tencent's response as "nonsense," insisting "the damage is done – and it continues" and accusing the Chinese company of trying to minimize its involvement by using "shell" entities even though the Chinese firm remains "at the helm."

"The copying was so egregious that numerous journalists and Horizon fans called Light of Motiram 'a major Horizon rip off,' 'an obvious knock off,' a 'copycat' with a main character that 'resembles Aloy to a tee,' and ‘extremely similar to Horizon Zero Dawn'," Sony wrote.

That's not all, though. As spotted by Games Fray, Sony has also filed for a preliminary injunction in a bid to prevent Tencent from using a red-haired character in Light of Motiram, as well as other visuals or storyline elements close to that of the Horizon franchise. It hopes for the injunction to be enacted by the end of the year.

Tencent, however, maintains that with a scheduled release date on Q4 2027, Sony "cannot possibly hope to demonstrate the ‘immediate threatened injury’ that is the prerequisite of a preliminary injunction" given the game is so far from release. It attached declarations from a number of key stakeholders, including Guerrilla's head of music, Lucas van Tol, and artist Jan-Bart Van Beet who both claim they were "shocked" when they saw Light of Motiram, with Van Beet writing: "Tencent’s promotional material presents a visual setting almost identical to SIE’s Horizon promotional material."

"After spending over a decade creating and developing the Horizon franchise, it was disappointing to see our work copied to such a significant extent," he wrote. "Instead of spending the years and money that we invested into creating the Horizon world, Light of Motiram simply copied it, sidestepping the investment we made — and significant risk we took — in developing Horizon."

He continued: "There is an even greater risk of harm to the Horizon franchise if Light of Motiram, once released, does not have the same high quality as the Horizon games. The confusion caused by Light of Motiram promotions has already interfered with our existing Horizon development strategy, as there is a risk that future expansion could be incorrectly interpreted as copying Light of Motiram."

Van Tol wrote: "I have reviewed the music and sounds in Light of Motiram's promotional materials. I found striking similarities between their promotional trailer and the Horizon music. Light of Motiram's promotional materials contain the same core features of the Horizon sound, including the pillars, instrumentation, intimacy of the lead female voice, melodic composition, and rhythm, creating a similar overall feel."

The case continues.
