XCOM 2: War of the Chosen is a major expansion to XCOM 2, developed by Firaxis Games and released in 2017. The expansion introduces powerful new enemies known as the Chosen, who actively hunt the player’s resistance forces. Three new factions—Reapers, Skirmishers, and Templars—bring unique abilities and strategic depth to tactical combat. Additional mission types, soldier bonds, fatigue systems, and improved enemy variety expand the campaign. With deeper strategy layers and intense challenges, it significantly enhances the core XCOM 2 experience.
