Darker and Darker's lawyer has accused Korean gaming company Nexon of "anti-competitive bully tactics", in a letter to Steam owner Valve.
Following positive reception at Steam Next Fest earlier this year, Dark and Darker has experienced a troubled production. In March, developer Ironmace had its office searched, after Nexon alleged the studio created its game with code stolen from Nexon's own "P3" project (something several members of Ironmace's team had previously worked on).
Soon after these allegations were made, Nexon issued Ironmace with a cease and desist demand, and Dark and Darker was removed from Steam. Most recently, it came to light that the Dark and Darker developer is being sued by Nexon for "copyright infringement", with the Korean game publisher demanding a jury trial in America.
