Activision has moved against Warzone Agent, a paid, unauthorised third-party app that let players check opponents' skill levels before joining a Call of Duty: Warzone lobby, a practice known as lobby shopping. Eurogamer reported that the crackdown, announced by anti-cheat team Ricochet on X alongside Modern Warfare 4's Warzone launch and Season 1, means players attempting to load the software will be blocked and told to unload it before accessing multiplayer. Ricochet said using unauthorised software violates Activision's terms of use and leaves accounts and hardware subject to enforcement, though Eurogamer noted the wording stops short of confirming bans. Ricochet also reiterated that boosting is cheating and said more than 20,000 boosting-related accounts have been removed since Modern Warfare 4 launched. Separately, Activision released a free trial of Modern Warfare 4's DMZ extraction mode on PC via Steam and Battle.net, PlayStation 5 and Xbox Series X/S, available until Wednesday 11 November. The trial covers only DMZ, not multiplayer or the campaign, and Eurogamer reported it appears to have no progression limits, including access to the new X01 endgame area. The trial arrives about two weeks after Modern Warfare 4's 23 October launch, and both DMZ and the new Warzone use the same Hajin map.
