Take Meld for example - a new resource that can be used to give your soldiers cybernetic implants like super pupils that improve your aim, chameleon-like skin that renders you invisible, and bionic legs that let you leap onto rooftops. So it's still the same taut strategy game about fighting turn-based battles against aliens before returning to base to research new weapons, launch satellites, build labourites, and sort out the world's ET problem.Īnd it has the same story, same missions, same mechanics, same alien enemies, and same cutscenes we described in our 2013 review. XCOM: Enemy Within is an expansion pack for XCOM: Enemy Unknown - not a sequel or a spin-off, despite arriving as a separate, full-price app.
