Activision is hardening its Ricochet anti-cheat system and will require PC players to enable Microsoft’s Secure Boot and have hardware supporting Trusted Platform Module (TPM) 2.0 when Call of Duty: Black Ops 7 is released later this year. The publisher begins a phased rollout of the safeguards on 7 August, alongside the launch of Season 5 for Call of Duty: Black Ops 6 and the free-to-play Warzone. During the test period the settings remain optional, but players who lack them will see in-game notifications. Activision says the hardware-level checks confirm a computer’s integrity at start-up and do not affect frame rates or other in-game performance. The company is also urging users to activate two-factor authentication and has filed legal actions against 22 individuals accused of selling cheats.
