I′m having trouble with crysis 2, I was about to play crysis 2 when it asked for the serial , its happened before and i usually just click next and enter the key thats on the manual since i bought a physical copy last year, anyways i dont have internet back at my home because, thats ′s how my life is , anyways , i entered it once again and it says it requieres internet to continue, so im stuck and i want to play since i dont have much. Is there a way around this?
