This expansion to the original SWAT4 video-game provides more campaign missions, maps, and characters, that can be used in the Quick Mission Editor alike. It also includes more weapons and features than the base game, and it launches as a separate application instead of a modular addon, which can be helpful in some ways but unhelpful in others. For example, your progress and quick missions will not carry over from the original SWAT4 to the Stetchkov Syndicate application, but the Stetchkov Syndicate application does include all of the original SWAT4 maps for use in the Quick Mission Editor.
