The Black Sect cannot be played in Multiplayer. Although there are several community-made mods (essentially hacks) which allow playing as them in singleplayer. In the original campaign for single-player, the Black Sect has invaded the region surrounding the Black Sea, and only appears towards the end of the game. They are often recommended to be the top priority to be eliminated. One of the in-game briefing line states that their "origin could be traced back to the earliest European secret societies, with all the requisite branches into the royal families".
