Firaxis Games announced a new expansion for XCOM 2 at this year's E3. War of the Chosen will add three new resistance factions, each with a unique hero class, to help aid XCOM in liberating Earth. However, ADVENT does not sit idly by, sending out a new force called the Chosen to recapture the Commander.

As an active hunting force, the Chosen will invade XCOM 2's strategy map and will kidnap, interrogate, and kill XCOM soldiers while working towards their objective. A new alien called the Spectre will also appear and is able to create dark copies of XCOM soldiers. War of the Chosen will be released for PC, PlayStation 4, and Xbox One on August 29, 2017, with a release for Mac and Linux coming sometime after.
