Blizzard’s taking cheating seriously in Overwatch. As their commercial success wades out into the pool of competitive play, the company is trying hard to ban cheaters and take action against the companies that are developing the hacks.

That goes for Bossland, creators of Overwatch cheating tools like “Watchover Tyrant.” This cheat essentially produces a secondary HUD for players that shows enemy location (through walls) and health pools. Players actually subscribe to this tool, speeding as much as €12.95 for a month of access. That’s like $15 a month for a cheat.

Blizzard’s officially filed a suit against Bossland for creating these cheats. The suit was filed with the United States District Court of the Central District of California. “[Bossland] and those working in concert with it have built a profitable business by creating, distributing, maintaining, and updating malicious software products that are specifically designed to enable their users to cheat at the Blizzard Games, at the expense of Blizzard and its legitimate customers,” Blizzard asserted in its lawsuit. ” These software products include four ‘bot’ programs – ‘HonorBuddy,’ ‘DemonBuddy,’ ‘StormBuddy,’ and ‘Hearthbuddy’ (the ‘Buddy Bots’) – that enable users to automate their gameplay and manipulate the Blizzard Games to their competitive advantage.”

Blizzard added that the profitability of their games relies on a fun and fair environment, and cheating tools like the ones made by Bossland “has caused Blizzard to lose millions or tens of millions of dollars in revenue, and to suffer irreparable damage to its goodwill and reputation.”

Blizzard argued that Bossland has knowingly violated lights of DMCA laws, and that they’ve “knowingly, intentionally, and maliciously induced thousands or tens of thousands of Blizzard customers in the United States to breach their contracts with Blizzard, including contracts that explicitly prohibit them from engaging in the precise type of cheating that Bossland enables by its hacks.”

Is Blizzard in the right, here? I’m no legal mind, but I assume they have something here that justifies the suit. Perhaps they’re simply trying to push Bossland to fight the case and run out of funds. That wouldn’t be a first in the business world.
