After beating the dungeon boss, nothing happens. Is something suppossed to happen?

There's only a target dummy to practice on it seems. There are no options in the menu to start a single player game. There's a button that's called 'Fight' but this does nothing. I can see on some gameplay videos that there used to be a button called 'Orks Attack' but this is now gone?...

Hi, can someone tell me if this game supports native Oculus SDK or must use SteamVR? Also, any plans to launch on Oculus Home? Thanks
