Another "Coming Soon" teaser that can be found on the FarmVille loading screen is for Co-Op Farming.
What exactly is Co-Op farming?
According to Wikipedia Co-Op or Cooperative Farming is "where farmers pool their resources in certain areas of activity." Farmers collaborate with each other by combining or sharing resources to help with the production, packaging, and distribution of their crops.
