Kudarat, single player and multiplayer of Mc5 are connected, they both require WiFi. You can simply finish SP (which is awesome), unlock great guns and use them! No "buying" is required in that game, you can use things by just unlocking it. I've played for less than two weeks and I've already unlocked the best smg with all the attachments. :)
