This popular puzzle has two kinds of multiplayer. First is the co-op, when you play with a keyboard or two joysticks, sharing one screen. It’s kind of the best solution for this game because you can talk, help your fellow, and punish each other instantly.
Unfortunately, in reality, getting together is a problem. And the Internet connection saves the party. 8 players join one server no matter where they’re sitting at the moment. However, a text chat might slow the process significantly, so you should consider a program to talk while playing.
