Counter-Strike co-creator Jess Cliffe, 37, has pleaded guilty to charges of sexually exploiting a minor, according to his court docket.

Cliffe first appeared in court on Feb. 2, and filed his guilty plea on Oct. 8. Cliffe was charged with soliciting sex from a minor through a website called Seeking Arrangement.

During the investigation, the victim, who was 16 at the time, told police that Cliffe paid her for sex multiple times, and videotaped their sexual interactions against her will.

Cliffe's sentencing hearing is set for Nov. 2.
