To recap: smart people are introducing multiplayer to the PC version of sandbox shooter Just Cause 2. A public beta was held last week, and another is just winding up now. It continues to look like just about the best thing ever.
Rather than only letting 4-8 people onto the game's enormous map at a time, the Just Cause 2 Multiplayer team have figured out a way to let hundreds over one thousand people on the same map. A map that's full of vehicles, weapons, grappling hooks and a comical physics system.
Human nature takes care of the rest.
