Call of Duty: Warzone 'enhances' its anti-cheat software By Cristina Criddle image copyrightActivision/Call of Duty: Warzone Call of Duty: Warzone has banned more than 60,000 accounts in one day for cheating on the video game. Publisher Activision revealed the game had its own “internal anti-cheat software”, which it was now enhancing following demands from players. Several high-profile streamers had criticised the battle-royal game for being “saturated with hackers”. More than 300,000 permanent bans had been issued since the game’s release, last March, Activision said. Other popular games such as Fortnite and Fall Guys outsource their anti-cheat code. “We are committed to delivering a fair and fun experience for all players,” Activision said in a blog post.
