Hi, I bought Crysis 3 (In a local store, not Origin) and downloaded Origin because you can't play without it, I have Crysis 1 (the one that comes with the pre-order) there too and now I'd like to add Crysis 2 (I bought it in a store too), but my question is, if I add Crysis 2 in Origin with the limited edition codes, can I still install it again without Origin? Or the code will be useless? I like to use Steam in all the games and using an Origin game with Steam have issues...

Thanks.
