As a part of the IGN First program, XCOM 2 has been announced to be releasing sometime this November, and for PC only.
The game will be releasing for PC, Mac, and Linux in November. No word on any console releases yet, but the premise of the upcoming game can be found below, with a trailer above:
In XCOM 2, the roles have been reversed, and XCOM is now the invading force. They are hampered by limited resources and must constantly evade the alien threat in their new mobile headquarters. Players must use a combination of firepower and stealth-like tactics to help XCOM recruit soldiers and build a resistance network, while attempting to expose the evil alien agenda and save humanity. XCOM 2 will introduce gameplay features such as procedurally-generated levels, which will make each experience unique to the player, as well as offer a much deeper level of modding support. Additionally, XCOM 2 will offer a variety of new content including five updated soldier classes, increased soldier customization, more alien and enemy types, evolved tactical combat and more.
In the coming weeks, IGN has said they will be interviewing Creative Director Jake Solomon and Lead Producer Garth DeAngelis of Firaxis Games. In those interviews, we will learn the reasoning behind the single platform idea, and how the game plans to help support the PC communities modders. Expect to see some gameplay in a few weeks during E3.
