I have bought a year ago HItman Collection (hitman 1,2,contracts and blood money) an out of curiositi I searched on steam store for the games and i saw blood money and contracts there and i thought maybe i can register them on steam and get steam benefits but i can't find the cd key (they aren't written anywhere . I opened a thread on steam comunity asking for adice and if i can registere the games there but they said that i must ask the developers if they can provide me with the steam keys (it was said in a general manner that "some developers have provided retail version buyers with steam keys" . Is it posible ?
