Im sorry to hear about this. Seems shitty, and is actually fucking insane to spend that kind of money to play a couple days early and for some reason it really pisses me off that they do this. I do have to say though it isn't a mistake I would have made. I thoroughly check before I buy something.
I haven't played a CoD game competativly since Modern Warfare 3. I've just downloaded the CoD4 remaster and jumped straight into multiplayer. 2.2 KD ratio.... yep still got it 🤣
I must say the game still feels utterly fantastic to play. The maps are still brilliant and came back to me instantly. One thing I can't quite figure out though.... if you don't use the air strike before you get the chopper is it just gone???? Keeps happening to me
