Developer Firaxis and publisher 2K announced the first expansion for XCOM 2 during E3 2017. Dubbed War of the Chosen, the expansion is the largest expansion ever released for the series coming in at twice the size of any previous expansion they have released so far. Last week the studios released a trailer showing off a new unit, the Skirmisher, today the team has released a new trailer showcasing The Warlock, which can be seen below.

In the new trailer we get to take a look at one of the expansions’ enemy units: the Warlock. The Warlock looks to be a menacing force to mess with utilizing necromancer like abilities to reanimate corpses. From the trailer it appears that the Warlock can also reveal a soldiers weakness by infecting them with the void and using that to its advantage.

XCOM 2: War of the Chosen will bring three new factions; the Reapers, Skirmishers and Templars. Each new faction has their own unique abilities and philosophies. The new factions will also provide new hero class soldiers to aid in battle. In addition to the new factions, the expansion will also include new environments and mission objectives.

XCOM 2 is currently available on PS4, Xbox One and PC. War of the Chosen is scheduled to release on August 28, 2017.
