Re: No Players PC Server change or combine of servers
To change the region for garden ops: when you are on the choosing to start a match-join a match- solo ops screen look at the bottom and it will have a button that says select region. I find europe region has the most players for garden ops.
For team vanquish and gardens and graveyards same thing on the first page where you choose multiplayer-solo ops- at the bottom there is a button.
I live in east coast and usually that time zone is dead during the day but europe always has multiplayer matches going.
Also you can ask friends to join a match if they are online. If you don't have many PC friends yet, you can add me. If I am on, I'll join your game.
