Rainbow Six Siege is one of the most popular multiplayer games on the planet, so it comes as little surprise that it has its share of imitators. One such imitator, however, is doing more than that in eyes of Ubisoft. The company has filed a lawsuit against both Google and Apple for selling a game Ubisoft says is a direct ripoff.

As reported by Bloomberg, Ubisoft's suit against Google and Apple concerns the game Area F2, a multiplayer shooter created by Chinese mega-corporation Alibaba and its website Ejoy. According to Ubisoft's suit, the game allegedly copies Rainbow Six Siege's user interface, including its final score screen and the operator selection screen. Area F2 is available in the United States on mobile devices and is currently in a free period, while Rainbow Six Siege is only on PS4, Xbox One, and PC.

Prior to filing the lawsuit, Ubisoft said it had told Apple and Google that the game infringed on its copyrights but the games were not taken down. The lawsuit was filed in Los Angeles, and neither Google nor Apple have commented on it yet.
