It's not perfect, but Firaxis has enhanced XCOM's core to create an unquestionable improvement on what went before. After spending the last couple of years reworking, refining and enhancing key elements of Civilization 5, the developer has now slapped XCOM: Enemy Unknown on the operating table, rolled up its sleeves and poked at the innards of what was already one of the best strategy games around.Īs a result, XCOM: Enemy Within benefits from the kind of base-level modification that typifies the genetically enhanced soldiers and mechanised brutes that serve as its own headline additions. When it comes to expanding upon on an original concept, Firaxis is not averse to getting its hands dirty.
