These are human beings after all, and thus they think like you.
However, the real challenge in fighting Exalt is the tactics they use when you meet them in the field. You will then enter either a sabotage mission where you sneak into their base and download information from their computer terminals, or king of the hill-type missions where you have to protect a transmitter you have deployed against waves of Exalt soldiers. After a given time you must then send in your troops to bring the agent back out. When you discover such a threat you can send one of your agents to spy on the terrorist cell that tried to sabotage your efforts. If kept unchecked Exalt can cause you some real trouble. In addition, they perform various sabotage missions that can drain your resources or ruin your research. This terrorist organization gives us a richer meta-game, where the organisation fights against you by spreading panic with their propaganda. It is here Xcom: Enemy Within get its literal meaning.
The terrorist group Exalt is working hard to prevent Xcom from chasing the aliens away. New this time is that not all people agree that aliens are a threat we should fight. Xcom is, as many of you probably know by now, a secret international organisation that specialises in fighting the extraterrestrial threat. Mankind, however, has predicted that this could happen, and thus dusts off the Xcom initiative. Aliens arrive at earth, and instantly show us puny Earthlings who's in charge. The story is basically the same as before in Xcom: Enemy Within. But I still felt there was something missing, and I have therefore had high hopes that this expansion would be able to add something to the elements where I felt Xcom: Enemy Unknown did not meet my expectations. When Firaxis relaunched the Xcom series last year they did so with great respect for the original, while making some necessary changes to bring the experience up to the level that today's gamers expect. This is no easy task that Firaxis has taken on. The rich meta-game combined with tactical ground fighting that hadn't been seen before in any video game created an experience and atmosphere that I do not feel has been exceeded some twenty years later. The original 1994 DOS game UFO: Enemy Unknown is the title that made me a gamer. Every time the name Xcom appears, it fills me with a wonderful sense of nostalgia.
