1. Is the name of the cave in the picture randomly generated?
2. Will I be able to hunt the moose to the left?
3. What's that little red circle on the minimap?
1. That's actually a whole dev diary on its own. Short story: we create regions and name them. They are randomly placed in the world. We have several different cave regions with different names, so you might not always see Cave of Lost Trolls in every game. We might do even more randomization of the names, so it might be "Cave of 12 Angry Trolls" or "Cave of Abandoned Trolls" or something entirely different. There might be bears there. Or wolves. It's only alpha, after all.
2. The moose... you don't want to mess with the moose.
3. That's a place of interest, you could call it. It indicates that there's something you should go take a look at. I did not take the screenshot, so I am not sure what's there myself.
