So a couple things I want to mention, it's all still WIP but you can play 100% solo if you want, you don't need players online to grow a tiger, wolf etc. there is food at every water source. In the main menu click on "whats new" it will show you all the food sources and a list of patches and changes for this build. please report all bugs to bug-report
have fun!
