Hello,When ordering the Gold version of Far Cry 4 everywhere is written that additional missions with Hurk, The Syringe, Bloody Rubin, Escape from prison and Valley of Yetis is available in both single and coop. I tried with a friend run the co-op mission but without success. We can only do side-missions, take fortresses or navigate the open world. When you turn on the game I choose contiue and then invite a mate. Where do I make a mistake? In fact, we bought gold edition especially for these missions in co-op and we have no way of completing them together. Can anyone clarify or explain what we are doing wrong? Thanks
