so i bought HAWX PC version from best buy, after installing the game i tried to play online and it asked me for a serial number. then i realized i dont see it anywhere in the case. where would this cdkey be? can someone help me pls? the packaging of the game is intact i dont think another person had stolen it o.o

The cd key is located on the back of the manual. If you didn't get one, you'll need to take it back to the store for a replacement.

thanks found it!
