1- Which fight in particular is giving you issues? (The first couple of fights on Skull Island are single player only, but you'll be grouping up in no time.) 2- Are you in the same realm? (Here's a page from the player's guide in case you are not familiar with realms)
This should be a quick-hit FAQ...My wife was ready to strangle me lol! Seriously tho, my 7yro and I LOVE the game. We both just started so b/c we haven't finished SI is why we cant fight.... we are both in the "tutorial mode" - so-to-speak.
The Realm was a very good idea, but I already tried that. The answer to the riddle is #1 of your support.
THANK YOU everyone - I knew it was something simple.
