i can't see the product key left 4 dead 2
sorry I've just realised that you can only use a CD key once ill have to ceap on looking for that key
It is a Key that will unlock the Left 4 Dead 2 in your steam library
On the back of the game manual/CD case, or on your Steam account.
No, you have to buy the game again, the CD key is your licence, without it you don't own the game
the code is on the CD ****-****-****-**** look for a code with that format if you need CD key buy new CD or buy a key online
It's as big as a regular CD.
Left 4 Dead 2!!
There is more then one CD key for security reasons they put one randomly generated CD key in every game and one use and it is not usable again
No
left 4 dead 2 can be downloaded from Steam
