Key Code problem

[Narko]

I dont know if this is the right place, if not, sorry about that. I bought a physical copy of the game at a fleamarket, but when I try to install it, it says that the key code is already attached to another Steam-account. Is it impossible to buy a used game these days? Can I get it to work somehow? The vendor that sold it to me couldnt help, as he didnt know where he got the game from. Hope someone can help.

Is the key code written on like a piece of paper?

If so you can contact steam support to activate the game on your account (their response may take 3 days...)
They'll give you an unique code that you must write on that piece of paper and take a picture of it and send it to them.
After a few hours they'll add the game to your steam library
(happened to me for Black ops II and worked)

it's 2016, you didnt know most pc games cant be reused? many console ones too, that's what those $10 online passes were about

the game would have to be standalone (not steam), which in call of duty's case is up to cod5 world at war... but even then you have to trust that the person that used the key in the past didnt cause it to be banned or didnt resell it to multiple people (so they wouldnt be able to go online at the same time)

now if you dont care about multiplayer & just wanted singleplayer, well... that's unfortunate yes, steam games are entirely tied to the account that activated the key rather than simply being the multiplayer feature like in the past

as a side note, may i suggest trying a lot of these free to play games like dirty bomb, warface, blacklight retribution, evolve, team fortress 2, planetside 2, america's army, gotham city impostors (almost dead?), tribes ascend (almost dead?), hawken
