Is Guild 3 multiplayer?

I'm curious, is Guild 3 a multiplayer game? I've heard so much about its engaging gameplay and rich story, but I'm unsure if I can share the experience with friends. If it is multiplayer, does it offer cooperative or competitive play? Additionally, are there any unique features or mechanics that set it apart from other multiplayer games in the genre? I'd love to know more about how I can connect with others and enjoy the game together.
