XCOM 2 is coming out later this year. IGN has the first information about the upcoming 2K and Firaxis game. XCOM 2 is the follow-up to 2012's XCOM Enemy Unknown. You can watch the reveal trailer below.
Oddly there is no mention of a console or mobile version. XCOM 2 might be a PC, MAC, Linux exclusive or more likely they are still working on deals with one of the console makers and that stuff isn't final yet. Regardless, I feel confident that XCOM 2 will come to consoles at some point. Probably tablets as well.
The story for XCOM 2 seems to be set around 20 years after the events of Enemy Unknown/Enemy Within. It seems the aliens have taken over the world and you are part of a small rebellion, trying to fight back the alien overlords. It sounds like a neat way to freshen up the XCOM series. You are now the invading army. You are the enemy attacking cities. Interesting.
We will probably hear more about XCOM2 at E3. As a huge fan of the last game, I am really excited to play this new game and I can't wait to see more. You can read more about the upcoming sequel at IGN. IGN also says gameplay footage is coming in 2 weeks.
XCOM 2 is coming out November 2015 for PC, Linux and MAC. No console versions have been revealed..yet.
