Looking to do quests with your friends? Just getting started? Not familiar with the game? Do you want to enjoy yourself?
Then do not look here. This game is filled with griefers and there is no way to play without them. If you are new to the game, you will not have a chance against those who devote their time ruining the game for others.
If you want to relax with your friends and do quests, you will likely not have a chance when three different player squads come by to screw everything up.
Don't know why a private server option is not available. You should give players the option to only play against AI. It is impossible to get into this game against players who have not left the game since the beginning.
Other than the griefers, literally everything else about this game is terrific. Environments are beautiful. Enemy AI are surprising and not too bad to deal with. Quests are fun. But those griefers will ruin your time.
