Steam has removed a developer’s games after Valve was subpoenaed for 100 users’ information in a nasty legal fight over user reviews on the games service.

James Romine of Digital Homicide was granted the subpoena by a federal judge in Arizona. He is seeking the real identities of 100 users in an $18 million personal injury claim against these users for their comments and allegations of the studio’s products and how they were developed. Storefronts for about a dozen games were taken down yesterday evening. (A screenshot of one of the games, The Slaughtering Grounds, is above.)

Valve has the right to contest the subpoena at a hearing. It’s unknown what its plans are. Polygon has reached out to a Valve representative but large companies generally do not comment on pending litigation or their plans in court.

Update: A Valve representative replied: “Valve has stopped doing business with Digital Homicide for being hostile to Steam.”

Romine has brought a separate $10.7 million lawsuit against the gaming personality Jim Sterling over videos he has made slamming the studio’s games. Romine and his brother, Robert, allege that Sterling’s audience and supporters have also harassed them through the mail. Kotaku published a lengthy examination of that dispute and its origins back in March.

YouTube personality SidAlpha reported the subpoena developments in this video on Thursday, likewise making a strong condemnation of the Romines’ actions and games. All of the documents related to the subpoenas can be found here.

Polygon has reached out to James Romine for comment on the latest developments with Valve.

Update: Digital Homicide has responded at length here, implying they will seek to bring a lawsuit against Valve.
