For XCOM fans with iOS devices, though, 2K Games is giving us a taste to tide us over in the meantime — iOS title XCOM: Enemy Unknown.
The game is sort of a reboot of the very first XCOM title, 1994's UFO: Enemy Unknown, and a port of the title already available for the PlayStation 3, Xbox 360, PC and Mac. As such, the core gameplay revolves around turn-based ground strategy as you lead squadrons of up to six soldiers against a new menace that is threatening the Earth: aliens seeking to use humans for their own ends.
To anyone who played the original title way back when, the game will be instantly familiar. After a brief gameplay tutorial, you choose your base — the US gives you a 50 per cent discount on aircraft, Europe on research facilities — and that "ant farm" base is pretty familiar, too. After each combat mission, you will return to regroup, and there are a lot of things you can do while there.
