Call of duty is the no. One best shooting game this is 3rd latest version of their series it required 6gb ram and 40gb hard disk space in minimum and it recommend 8 gb ram and 40 gb hd space it have impressive graphics so anybody not leave this game because its a very interested game and other feature is it include 2 way play of game one is multiplying and single playing . Ilove the single play because it is the most trilling method
