1. Can I tame those red orcs in 0.27 ?
2. How can I get to Orc's camp after get glafire stone?
1) No, you can't. But you can have a positive relationship with them so they won't fight you. (They will just want to have sex with you)
2) You can go there - but nothing will happen... But hopefully Hyao adds the Orc's camp soon, I personally think it might take a little while since he's rewriting the code - plus some more areas need to be added in from what I remember reading.
