With the newly released Social Module, players in Star Citizen can now explore various places outside the hanger. There's the first planetary landing zones ArcCorp's Area 18 that you can explore with up to 24 other players. There is a chat system and some emotes you can use to talk to and interact with other players.
"The Social Module represents our first step into Star Citizen's Persistent Universe. In the coming months, you will begin to see Star Citizen's formerly-disparate modules come together into our long term vision for the game," the developer says. "We wanted to open up a bit more of the Star Citizen universe to the community, and allow people to get a sense as to what some of the various cities you’ll be able to visit will look like."
You can read the entire post of the developer at the official site and learn the idea behind the Social Module as well as the future plan.
