XCOM: Enemy Unknown
Like playing a game of chess with GI Joes and aliens, the aim of this super-cerebral strategy game is to know thy enemy
In the event of an alien invasion it really is important to learn to prioritise. And to juggle. In XCOM: Enemy Unknown you are plunged into the middle of just such an invasion. As the commander of an elite anti-alien unit you are responsible for the building, running and expansion of your XCOM base and its operations.
