I know just how dumb that sounds but MW is my first ever COD.

I was about 4 hours in and discovered there was a remaster. So I stopped, went and got the remaster and put it on. The pictures are the 2 games im talking about here (duh, I know right)

MW Campaign literally threw me straight into it all these mini stories but the remaster has me having to do training, how to use a gun, assault course that kind of thing.

If it's just a remaster how are they so different? Have I done something dumb here ?

Apologies for the really noob question here, don't wanna miss playing the original MW which I was really enjoying if it's in some way different.

Thanks all!
