Guy fights evil corporation after being an assassin commando in their employ...he joins rebels and then fights back in isometric top down kick ass gameplay style through various WEC installations and locations as you attempt to help the rebels win the day.

Also the nwo in the game is World Economic Consortium(in the second game it's the Lunar Mining something or other), and the plot is similar to oldschool red faction...albeit as I said in topdown third person shooter mode. It's a good game though once you get the hang of the controls.
