Hehe xD Haven't tried MW2, but i've heard that the Echo Spec-Ops missions are a huge pain.
If they are half as hard as some stages in Demon's Souls, then yes, be prepared for a long break sometimes :P
My biggest one was when I lost 400K souls due to a single stupid mistake of dodging towards a cliff, after I had died and lost the 400K souls due to a pincer attack. Just like that, 4 hours of work and grinding, 6 Soul Levels lost... I just wanted to punch the PS3 xD
