4 came out a while ago. And yes there is a 5. Personally I don’t like it just because of the fact they went back to WWII and all the guns are old and not all spiffy like they were in CoD4. The game looks good but it’s still pretty much the same as CoD4 as far as game play goes. They added in some new weapons and the like but I’m not really a CoD fan so you’ll probably hear more positive feed back from other people.
NOTE: I am NOT saying this is a bad game, it’s just not great.
