The kernel-level driver, according to reports, is now active on PCs for those in North America following a small update for PC on The news broke at roughly 07:00 GMT on 15th December.

Ricochet is a "multi-faceted approach to combat cheating" which is supported "by a team of dedicated professionals focused on fighting unfair play."

That's the first layer of protection. The second one is the kernel-level driver for this anti-cheat system, running on your PC and is required to play Warzone.
