Daniel at GameCloud writes: "XCOM Enemy Unknown was successful at rebooting the series and modernizing the classic strategy because the changes were enough to welcome new players, but not enough to scare off veterans. However, Enemy Within seemed to have missed the memo and feels rushed; maybe in response to the backlash from the “Slingshot” DLC? While some of the bugs can be overlooked and worked around, some of them are inexcusable. Ideas such as the new aliens and EXALT are interesting, but are simply not fleshed out enough to make a significant impact. Additionally, the new unit types are fun but grossly overpowered, and this doesn’t work either. It’s clear that Enemy Within understands the concept of what makes a great XCOM game, but drops the ball in the areas that count. With an assortment of bugs, glitches, and unbalanced additions, its difficult to recommend whole-heartily."
