Really? Hmm, I Had Trouble With That One, But, I Did Not Chuck My Controller Once, In Cod 4, I Chucked It At least 10 Times, I Broke 2, Damaged One, On Both Spells When I Played That Game In '09 and '11 , Especially That No Fighting In The War Room. MW2,
Only Hard Bit IMO Was The Favela One. And MW3, Easy Peasy!
The only level that caused me to swear a bit was when you started on the beach with the tanks; got to the walls but when i was told to head up to the right ever blinking time i got done; took me around 30mins to get past that area!
