The people who know whether it is possible for example with pirates insert filiki guns Chris and Jill in the folder with the game the incentive?Ride this or not who knows please confirm?And specifically what are the files responsible for this?Do not want to pay 300 rubles for these two guns to stupid to download a couple falicov from steam, I think easier with a pirate to add them and be done with it.
