The number of units gamers start off would be limited so gamers would have to take extra caution not to let their researchers and scientists get into harm's way. The feature in this FPS game would be the inclusion of skills to the units and the gamers. Some missions require gamers to plant a bomb and they have to select the demolition expert to the area. Although unskilled characters can also do the same job, they will take a longer time to do so. Time is an essence here, as sectoids are fast moving aliens.
Alliance also adds to another level of humanity to any game in existence.
With the ability to build bonds with the fellow teammate. Alliance will makes use of a system of attitudes and emotional states that influence trooper behavior. This behavior is apparent in everything the trooper does, from what he or she says to how he or she moves. Some of the animation and audio cues will be so realistic that it will give a eerily human feel to it. This game is expected to be released in early 2001.
