hmm.. it's been a while but as far as i remember, they are like 2 separate games..
so there should be 2 separate cd-keys, one for crysis wars and another for crysis warhead..
someone back me up here??
No, in the case of the Maximum edition, the customer would recieve one key for Crysis, and one key for Crysis Warhead which also works for Crysis Wars.
Odd... never noticed that?
Even if you just buy Crysis Warhead, you only get one key that also works for Crysis Wars.
