My biggetst gripe. and this may be a rant. but i will do my best to watch my language.
My biggest gripe with Sc4 is "The Tower Of Souls" mode. because if your new to the series, or are not very skilled in the defense and Offense than your going to get your butt handed to you on a regular basis. due to 2 things....1: your opponents seem to get the high powered skills. and 2. any damage you take or team mate you loose stays with you through the entire mission! so if you know your on a floor with an opponent your having troubles beating be prepared to reset the mission over, and over, and OVER!
