Playing games can be hard enough without cheaters runing the experience for others. At least that is at the heart of a court case filed by Blizzard against Bossland GMBH, a German company that makes cheats for games.

The cheat in question (via TorrentFreak) is Watchover Tyrant, a mod that lets players in Blizzard's popular FPS to see the health localtion and field of view of enemies and friendlies. The company also makes mods for other Blizzard games, including World of Warcraft, Heroes of the Storm and Diablo 3. The suit claims that Bossland's sale of these hacks in the United States has caused it "to lose millions or tens of millions of dollars in revenue, and to suffer irreparable damage to its goodwill and reputation.” It claims violation of the DMCA anti-circumvention provision, unfair competition and copyright infringement.

Blizzard continually takes action against cheaters, and apparently has nuked the accounts of players using the Bossland hacks. In response, Bossland has said it plans to make the mods harder to detect.

“Defendants not only know that their conduct is unlawful, but they engage in that conduct with the deliberate intent to harm Blizzard and its business. Blizzard is entitled to monetary damages, injunctive and other equitable relief, and punitive damages against Defendants,” according to the complaint, which was filed in California district court.

Bossland doesn't appear to be too concerned, despite not having seen the case yet. “There are over 10 ongoing legal battles in Germany already,” CEO Zwetan Letschew told TorrentFreak. “Now Blizzard wants to try it in the U.S. too."

Letschew said that a German court ruled against Blizzard in a similar case earlier this year regarding a Heroes of the Storm bot made by Bossland. Blizzard was ordered to pay court costs and attorney's fees.
