Warzone 2 and Modern Warfare 2 has a new set of patch notes for the May 31 update, which brings some pretty big nerfs to the current meta.

Modern Warzone 2 and Warzone 2 is continuing to evolve throughout the seasonal updates, but often the devs will hit players with in-season patches to shake things up and fix bugs.

The May 31 update is here for both games, and it includes some pretty drastic nerfs for the ISO Hemlock and Cronen Squall, which are two weapons that have been extremely popular in Season 3 Reloaded. Here are the full details.

ISO Hemlock & Cronen Squall nerfed

The meta ISO Hemlock Assault Rifle and Cronen Squall Battle Rifle have been dominating lobbies, especially in Ranked Play. However, that may now change as both of these weapons have been hit with nerfs in the May 31 update.

  • Cronen Squall
