Call Of Duty: Warzone has taken some strength out of the overperforming Ghost perk, and has also tweaked several other perks in an effort to “provide players with a variety of tools to create even more interesting stories”.In an update to Warzone detailed on March 28 (via The Loadout), Raven Software has shared that it wants “counterplay and interplay between systems to be viable” so that players can “create even more interesting stories”.To that end, the studio added that “perks are going to make for a significant part of the push towards this objective,” and has outlined several fairly major perk changes that arrived in yesterday’s Warzone update.The biggest change targets Ghost, and makes it so that players will only receive the perk’s stealth effect if they are moving. Raven Software explained that “in Caldera it is obvious that [Ghost] has become even stronger”, and felt that more counter play opportunities were needed for the perk.The update also makes changes to the Scavenger, Restock and E.O.D.
