15 levels isn't enough, but you still have the urge to play it over and over again!
THE BAD: Some missions are just impossible, no new units or structures.
I am a huge C&C fan and C&C the Covert Operations is difficult as hell. There are 15 expert missions which you can select in any order (no story, just pick a mission and play!), each of them vary from simple build a base and destroy the enemy to stealth missions. I much prefer the original C&C, but this package provides an excellent challenge. The game is good fun too and makes you determined to complete the mission once if you fail. However, although it's so far so good, C&C the Covert Operations provides no new units or structures and some missions just feel impossible no matter how much you try. Only get this game if you are a fan of C&C or an expert because some missions make you feel so frustrated you just want to throw your PC out the window. Anyway, to recap, the Covert Operations is a good little expansion but ONLY if you love C&C or are an expert RTS gamer.
I play this through C&C First Decade.
