Sony is suing Tencent over Light of Motiram, the publisher's open-world survival game that looks an awful lot like Horizon Zero Dawn.

PlayStation claims the China-based developer's upcoming game "Light of Motiram" is a "slavish clone" of its "Horizon" series.

Now, Sony is suing Tencent for copyright and trademark infringement in California federal court, calling Light of Motiram a "slavish clone" of the Horizon games.
