Call of Duty has introduced a plethora of gameplay changes in Warzone Season 4, such as Buy Station adjustments, Perk updates, etc. The tweaks might be minor in some cases, but their impact on the title is significant. For instance, players will begin the Gulag matches with a single Armor Plate. This incentivizes them to play it strategically instead of running and gunning.With that out of the way, let's take a quick look at all the gameplay changes in Warzone Season 4.Exploring all the gameplay changes in Warzone Season 4According to the official Warzone Season 4 patch notes, the following are all the gameplay changes:General GameplayGulagPlayers will now start with a single Armor Plate equipped in the Gulag.Developer note: This change seeks to help players in scenarios where no armor would result in certain weapons killing faster than intended - faster even than in Multiplayer - due to Warzone’s higher damage-per-shot values.
