Buy XCOM: Enemy Within Steam Key

Q: Why is the Steam Key of XCOM: Enemy Within safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download XCOM: Enemy Within to your game library. The account format requires more complicated steps and is more prone to errors during activation.

El precio es inmejorable, en su momento solo jugué el juego base, 100% recomendado. Lo pillé por YuPlay, 20 centimos de comisión, mucho mejor que otras opciones.
