While there are already server-side anti-cheat aspects of Ricochet active since the release of COD Vanguard, the full anti-cheat package didn't even make the launch of Warzone Pacific Season 1, which means cheaters are running around in Caldera.
The kernel-level driver, according to reports, is now active on PCs for those in North America following a small update for PC on Battle.net. The news broke at roughly 07:00 GMT on 15th December.
