So, the aim of source 2 is the production, to make it more effective while producing more and more content, so why not...


Simple, 2 or more people on the same map building on it. This can be quite (well, A LOT for me) if you are..

• Going to show an error to a friend
  
• Show progress to only one person
  
• Don't know how to do something, ask help from a friend
  
• Show your methods (and his!)
  
• Wanting to map more effectively
  
• And many other!

Please valve, add this. This will surely make ubisoft cry (MUAMHUMAHUMAUHM)!
