Which call of duty was the best?

Which call of duty is the best one? i'll have to go with mw2

BO2 was the best for me, also the first where i get all the unlocks

All but 1st one.
Good series overall, just not worth to buy.

I really justplayed Black Ops 1 zombies and that was that was fun enough for me.

That was also the only game where i bought all the expansion packs, a mistake i rarely do now.

cod black ops 2 by far but the first world war was amazing too

black ops 2 in my opinion, only the Zombie Mode is the best of all

I also think that everything except the first, because it went fart some

1ST ONE think Infinite Warfare looks great and I'm really looking forward to picking it up when it comes out.

personally I think MW3 was the best COD, everything was just perfect, i wish they would remaster it.

The best call of duty had to be the very first one ever . Without it all the others would have never existed .
