Destructoid - 9/10Enemy Within is an improvement on an already excellent game. For every decision that must be made there are several factors to consider, rarely enough money to pay for everything, and uncomfortable consequences to be faced for failure. All of this is exacerbated still further when playing on Classic difficulty or with Ironman mode enabled, where you're constantly worrying about what to do next or second guessing the action that you've just taken. Much like the genetic modifications that it champions, XCOM: Enemy Within is an experience that gets under your skin.
Polygon - 9/10If you haven't played the newest XCOM yet, now is a perfect time to do so. For all the XCOM veterans out there, you'll find a solid amount of new activities to engage in, as well as an unprecedented amount of squad customization. In other words, this is now the definiive Enemy experience.
Gamespot - 8/10Enemy Within forced me outside of my comfort zone, but provided enough reward for doing so that it became a continuing source of enjoyment. On the whole, Enemy Within plays like someone, somewhere kept a list of every minor thing they imagined, while playing Enemy Unknown, would make that game better — and then made those changes.
More information.Enemy Within is great, but its greatness comes with qualifications. Players who have never played XCOM: Enemy Unknown will find their best entry point here, since it remedies some of the concerns of the original and manages to keep others from taking their place.
